Hello!

Babies born during the Covid-19 pandemic met fewer communication milestones in their first year of live, according to new research.

But the news isn’t all bad, with the study revealing that ‘pandemic babies’ reached other milestones earlier.

The Royal College of Surgeons in Ireland (RCSI) study looked at ten developmental outcomes for 309 ‘pandemic babies’ at 12 months of age. These babies were know as the CORAL group. All of these babies were born during the first three months of pandemic in Ireland.

Parents reported their baby’s developmental outcomes, including:

  • crawling
  • side step along furniture
  • stand alone
  • pick up tiny objects with thumb and index finger (pincer grip)
  • stack bricks; finger feed
  • know their own name
  • express one definite and meaningful word
  • point at objects
  • wave ‘bye-bye’

These outcomes were compared a year after the babies’ births, with those of 1629 infants who were born before the pandemic, between 2008 and 2011 in Ireland. This group was known as the BASELINE group.

They found that the ‘pandemic’ babies:

  • were born slightly earlier
  • more were able to crawl by 12 months (97.5% vs 91%)
  • fewer expressed one definite and meaningful word (77% vs just over 89%)
  • fewer could point (84% vs 93%)
  • fewer could wave bye bye (88% vs 94.5%)

“Our research showed that CORAL babies were more likely to be crawling at the age of 12 months than their BASELINE counterparts, which might be because they were more likely to have spent more time at home and on the ground, with siblings home from school and parents working from home or isolating, rather than out of the home in cars and strollers,” Head of the Department of Paediatrics at RCSI, Professor Hourihane, said.

“However, lockdown measures may have impacted the scope of language heard and sight of unmasked faces speaking to them, while also curtailing opportunities to encounter new items of interest which might prompt pointing, and the frequency of social contacts to enable them to learn to wave. However, due to the observational nature of this study, more research is required to determine cause and effect.”

The researchers say that social isolation during the pandemic appears to have impacted more on babies’ social communication skills, rather than motor skills. However, there’s further research being undertaken.

“Due to the pandemic there were limitations to this study including comparison to an historic cohort. We are currently analysing results from year 2 standardised developmental assessments in the CORAL cohort of children and this will give us a better assessment of communication in this group of children,” said Dr Susan Byrne, RCSI Department of Paediatrics and FutureNeuro, SFI Research Centre for Chronic and Rare Neurological Diseases, and lead author on the paper.

“Babies are resilient and inquisitive by nature, and it is very likely that with societal re-emergence and increase in social circles that their social communication skills will improve. However, this cohort and the global population of pandemic babies it represents will need to be followed up to school age to ensure that this is the case.”

Did you have a baby during the pandemic? Did you think their social communication was impacted? Let us know in the comments below. 

  • I really dont think it matters at all. They would have learnt other things instead and im not sure why their speaking would be delayed. I would have thought it would be more advanced.

  • I dont understand how this could be so. Surely in a child’s first year of life, most of their social interactions are with family, which still occurred during covid

  • Isn’t really surprising that communication skills of covid babies were behind. When you have no interaction with people then you have less opportunity to learn communication skills

  • It’s an interesting read. I worry more about my older kids post COVID than I do my youngest who was just a baby when it started. The older kids are a lot more aware of it and worry about remote learning again and not being able to play with their friends etc, whereas my youngest doesn’t worry about that.

  • We will see the impact of COVID for so many years. I don’t worry about the bubs during the COVID years because I think they will catch up (and it’s not like they remember any of it) but I worry about the teenages and what lasting affects it has on them

  • Makes sense but wonder if they will compare them to kids at say 3 or 4 will they have caught up?

  • Interesting read. I’m sure each child will catch up and meet milestones

  • It’s understandable since they only had interaction in their own home. Won’t take them long to catch up though

  • It does make sense.

  • My youngest was born in 2019 so the year before the lockdowns started and she talks more and asks more questions than any of my other kids lol

  • I’m not very surprised by this study. It’s common sense to some extent.

  • It makes sense if they’re being confined to the house a lot more.

  • I had my son Jan 2022, so at the tail end of the pandemic, we didnt have lock downs by then (so happy about that) and we went outside every single day, I talked to him all the time and kept the chatter of conversation up (usually so I wouldnt fall asleep myself) and he started daycare at 4 months because he was just so excited to be around other children and explore new places. He was late crawling but early walking and says a handful of things, but you can see his is really trying to mimic how I say words etc so I dont think it will be long before he just starts talking and probably wont stop.

  • I can certainly imagine that isolation has impact the development and mask wearing impacts the speech development


    • It is so good that children are back in the community and getting opportunities to play and learn.

  • Definitely agree with this article. My daughter was 3 months old when the first lockdowns occurred and basically spent her first 2 years in lockdown. At 3.5 years old she still has severe social and separation anxiety. It’s unfortunate and it’s tricky trying to help her gain her confidence.


    • Aw bless, hope she can catch up !

  • An interesting article and study to follow.

  • My eldest was born in 2020 right in the middle of the pandemic. Hes almost 3 and is exceptionally good with his speech. He doesn’t go to day care and is more advanced that his friends who do. So I don’t really to this article with either of my babies. Its the time and effort you out in with your children

  • I would have thought the opposite would have happened with more time teaching and talking to the young. Guess the extra time was taken up with the phone rather than their child. Such a pity!

  • I hated not being able to smile at babies when I did my shopping.

  • There was good and bad in the situation and i think its going to be challenging
