But with fewer children at or above the expected level across England, charity Action for Children has called for urgent investment to prevent a ‘childhood crisis’.
At the age of two, children are invited to undergo a developmental check to see how they are progressing mentally and physically.
The comprehensive check sees health visitors assess the child's communication, social interaction, problem-solving, fine motor skills, such as holding objects and drawing, and gross motor skills, such as walking without falling and kicking a ball.
Data from the Office for Health Improvement and Disparities shows 87 per cent of Nottinghamshire children reviewed met or exceeded expectations in all five areas in 2020-21, up from 83 per cent the previous year.
However, across England, the proportion of toddlers achieving in all areas fell slightly to 82.9 per cent, from 83.3 per cent the year before.
The biggest decrease was seen in the development of personal and social skills, which dropped from 93 per cent to 90 per cent.
Imran Hussain, AfC director of policy and campaigns, said: “We know the first few years are critical to a child’s development so the fact they have spent the majority of this precious time unable to socialise with family, spend time with other children or enjoy normal levels of play has been devastating.
"Our frontline staff see this every day with children of all ages struggling with their speech, behaviour, education and social skills."
The figures show in Nottinghamshire, about 99 per cent of youngsters were on track with their fine motor skills, while 93 per cent had adequate gross motor skills.
Problem-solving was on target for 97 per cent of youngsters and 89 per cent were above or exceeding expectations around communication skills, with 96 per cent able to socialise at an expected level.
A Government spokesman said it was committed to ensuring every child has the best start in life, adding: “The NHS, local authorities and health visitors are working hard to reinstate services to help families get the support they need, and the Public Health Grant will continue to ensure investment is made in prevention and frontline services like child health visits.”
