The HSE says public health nurses who were redeployed to Covid19 activities are now returning to their core duties.
It comes as figures show a sharp drop in the number of assessments carried out on babies during the pandemic.
HSE figures show 53,524 babies had their checks on time in 2019, while in 2020 the figure was 28,184.
Dr Colman Noctor, Child and Adolescent Psycho-analytical Psychotherapist, says lockdown could have a wide-ranging impact on babies:
"As a child maybe hits... beginning to socialise, and that's kind of six months, 12 months, 18 months, there's a huge amount of exposure that becomes just par for development. So they see friends, they see different faces, they hear different voices, they are in different places. they might be out in different family settings, whatever it might be, and children in the last two years haven't had those opportunities".
