Have you seen this study?

Impact of the COVID-19 Pandemic on Early Child Cognitive Development: Initial Findings in a Longitudinal Observational Study of Child Health

It’s still in preprint, but it’s making news.

Babies born during the pandemic have suffered a significant drop in verbal, motor, and overall cognitive development.

A scary drop.

As in from 100, an average standard score, to 78.



For those of you who don’t routinely interpret test scores, here’s the classic reference for IQ tests, although the numbers may differ slightly depending on which test is used:

  • 130 and up: Very gifted
  • 120 – 129: Gifted
  • 111 – 119: Above-average intelligence
  • 90 – 109: Average intelligence
  • 80 – 89: Low-average intelligence
  • 70 – 79: Borderline intelligence
  • 69 and below: Extremely low intelligence


So… in real life language…

We’ve got a problem.

A gigantic worldwide problem.


Babies born during the pandemic ( that’s 2020 until… who knows?) are not learning (or walking or talking!) at the same pace as babies born before the pandemic.


The study is from Rhode Island Hospital and Brown University (for our readers around the world, Rhode Island a very small state in the Northeast US) as a part of a longitudinal, or ongoing, project to track child neurodevelopment beginning in 2011. Authors compared scores from the preceding decade (2011 – 2019) to babies born in 2020 and 2021 using The Mullen Scales of Early Learning, a well-known 5 domain developmental assessment that many therapists use and trust.

Scores were down across the board – in motor, cognitive, and verbal skills.

Guess who seems to be most affected?

Boys and kids in families with lower socioeconomic resources – not a surprise to those of us who see kids with learning differences.

Even in the absence of illness, environmental changes due to the pandemic are resulting in significant developmental delays. A year and a half of stay-home restrictions, school and educational/therapy program shut downs, masks, and social distancing, not to mention parental fears of illness and unemployment, have all taken a toll on everything – including how babies acquire new skills.

We should have known it was coming.

There have been very few opportunities for the kinds of experiences that drive early development- exploratory play outside, social interaction with new adults in new places, and playdates, birthday parties, and playgrounds with other kids.

I am hearing this at too.

Initially during the early days of the pandemic, an occasional therapist would send me an email wondering about this very thing.

Now, I get several emails in a week that read something like this…

“I just went to see my grandchild this weekend and I am very worried. Although I have seen him often on FaceTime since he was born, I had no idea of how behind he is. He’s just turned 18 months old and I did not hear any words the entire time I was there. Mom and Dad are not concerned. What should I do?”


“I’m an SLP and I am very worried about my neighbor’s baby who was born during the pandemic. She has rarely been outside their tiny apartment – not even to the store.”


“I went in for a well-baby check today and my pediatrician said he would refer us for a speech eval, but he doesn’t think we can see someone for a few months because the waiting lists are so long. Should I be worried?”


As a therapist, I bet you’re hearing this too.

If not, you will!

I’m certainly not going to stop talking about it!


What are we going to do about this avalanche of toddlers and preschoolers with global delays coming our way?

We’re going to rise up and help!

SLPs and other EI professionals are uniquely qualified because we already understand babies and families and how little changes implemented consistently can make huge differences and pretty quickly too!

We have a TON of advice we can give families and I’ll start sharing those specifics soon – so you can share them too!

Until then…

The study is a pretty easy read – as far as research goes! – so here’s the link if you’d like to add it to your weekend to-do list.

Blessings to you…

Teach Me To Talk Testimonials

Happy Therapists, Teachers, Parents & Children

"Laura Mize, you are a Godsend. I don’t know how one human can have so many helpful things to say in a beautifully organized way, so often. Always amazes me when another super helpful email comes from you, and for free. With free YouTube videos and cheap CEUs. THANK YOU!!!"

Sheila, Canada

"I purchased the book on autism and have watched the #400s series podcasts. Laura Mize has been more effective in teaching autistic tendencies, than many professors, shadowing professions, and the 100s of books, articles and classes or videos, or live workshop speakers, have been at teaching effective practices for a child with ASD. Some of the many lessons she has taught, which I will now use, to be a more effective Interventionist, include but are not limited to: red flags, typical behaviors, self-stimulating behaviors, not taking away toys, rather showing child to play with toy appropriately. She gives examples of child's actions, "inappropriate," explains the reason for: why the child is engaging in these behaviors and how they can be replaced with more appropriate, effective fuctional and age-appropriate skills."

"I’m sure Laura gets these messages all the time, but I thought I’d share. I stumbled across Laura‘s "Autism or Speech Delay?" YouTube video when I really needed it. This video finally listed and explained some of the red flags my son was showing for autism. I share the link anytime a parent is questioning in my FB autism group. This mother I don’t even know said Laura's video changed her life. I know exactly how she feels because It changed families too. Thank you to everyone at Teach Me To Talk."


"Good Morning Laura,
I received your book (The Autism Workbook) yesterday and it is absolutely amazing! As I evaluate young children (0-3) for developmental delays and write plans for them with their parents, there are a ton of ideas that are ready to use. Others that reinforce what I have been doing, and saying, all along. Thank you so, so much for writing this incredible book and pulling everything together in one place!"


"Thank you very much for sharing your knowledge, experience, and guidance.
I’m a parent who bought the autism workbook and it’s the only clear resource I found to make a change in my son. I’m really thankful to Ms. Laura for helping out people like us all over the world."

"Laura Mize, all I have to say is that ALL YOUR STRATEGIES WORK."

ANNE, YouTube viewer

"We have 7 SLPs in our preschool (public) program for special needs children (ages 3-5) and we use your courses, books, and techniques every day! :-) We have seen our preschoolers make such great gains!"


"I just received Teach Me to Play With You, and it is ALREADY WORKING! WOW!

Girl…my son is 3 years old, and he NEVER asks for something using words. We were playing “Get Your Belly” (from Teach Me to Play WITH You), and after several times, he laughed and screamed "BEWIEEE!!!"  It was a hoot. And I can't believe he said it! I have played with him like this before, but this time I took your advice and acted CRAZY!! I will act like a total lunatic if it will get him to talk to me!  Now I can give him "the look" from across the room, and he will say it. That manual is so amazingly practical, and it is a GODSEND right now! Thank you SO MUCH!”

"I wanted to send you a quick email to say thank you. I started watching your videos/podcasts about 4 months ago. My son has gone from losing words he previously used, only having about 7 words at his 2 year check up in August (assessed at a blended 10 month language level) -- to now having so many words, increased social engagement, following commands, spontaneously requesting things, and naming letters & numbers (not in order) as well as colors. We had our monthly meeting with our SLP through the state infants & toddlers program and it felt like we were just bragging the whole time, but I knew in the back of my head it was because I have been using strategies you taught me.

We still have so much work to do with our sweet boy, but I know in my heart he would not have succeeded without the education you provided. I will continue to read your emails & watch videos as we go along this journey and face challenges, but credit is due to you, Laura.

Thank you so much, endlessly."


"I just want to tell how fortunate I feel to have found your website and you!! I became a special instructor in EI almost a year ago and I started with hardly any applicable training. I felt so lost and confused as how to help the kids I work with learn how to use words and play. Honestly, I didn't even understand the importance of play, although I always played with my kids. But, once I started to watch your podcasts and get some of your manuals I felt a weight had been lifted off my shoulders and that I could finally teach these kids and their families something of value from a real therapist and based on research!. Thank you so much for seeing the need to help other EI service providers and providing a forum to share your knowledge and years of valuable experience. I'm sure you get a lot of these emails every week if not every day, but I wanted to make I could add to those notes of gratitude!! THANK YOU again!!"


"Just wanted to say a HUGE thank you for these emails and your books, I have them all and they have seriously saved and improved my sessions with my kiddos. Huge thank you."


"I was very frustrated with how speech therapy was going for my child. I would take him and drop him off and not hear much of anything from his therapist and teachers other than, "He had a good (or a bad!) day." Your materials were invaluable for us because I learned how to work with him on his speech. I learned how to teach him to talk and play. I learned how to pay attention to his cues and work with him to teach him to communicate. Without it, I have no doubt he still wouldn’t talk."


"Hi! I just wanted to say (from an SLT perspective) how incredibly useful I am finding absolutely all of your articles, blogs and resources - I only discovered your site last month and have just received all your books which I feel I am learning more than on my entire university training course!! But also the way in which you give specific, realistic, fun, encouraging ideas for working with parents is really just fantastic, I only wish I have your site sooner! Thanks so much from the UK! Kind regards."


"I just wanted to reach out to say thank you for making things a little easier to manage for me this year. I made the transition from school SLP to private therapist about a year ago. While the change was welcome, it was a lot, and I was just getting my footing in the clinic when I began teletherapy full time. Your website has been a huge lifeline in helping me work with late talkers and coach their parents in an accessible but effective way, even remotely. I look forward to getting your emails each week. I am floored by the amount of valuable, free information that your website provides, and I’m looking forward to investing in your workbooks soon. A sincere thank you for all you do!"


"You are an inspiration! I am truly grateful for the way you put into words and writing how to do what we do as SLPs. At this time in my 13 years of practicing, I find your encouragement keeps me going. As a single mom, I find it a stretch to buy materials these days and I am so thankful for the freebies you so generously share that help me teach my families. I don’t have much time to put together lists or quick references for parents!! Much gratitude!!"


"I just really appreciate your courses! I have two new clinicians that I’m working with and have recommended these courses to both of them. I’ve watched quite a few and have learned so much about serving this population. To be honest, before I started implementing your strategies I was a little frustrated with the lack of progress. My skills with engaging these little ones have improved so much! Thank you so much for making these CEUs so valuable!" C, SLP
