Babies born in the first lockdown were slower to meet developmental milestones.
That's according to research from the Royal College of Surgeons Ireland.
It showed babies learned to crawl sooner but were slower to wave bye-bye or point to something new.
The study compared a "pandemic cohort" of 309 infants born in Ireland between March and May 2020 with historical data on 1,600 babies born between 2008 and 2011.
