"My child cannot see facial expressions or body language. She can't recognise people at a distance; how will she manage in the playground?"
If your child has a sight problem, they might sometimes find it difficult to interact with others and so need extra support from staff.
Encouraging children to socialise
Your child's name will already be on the school's special educational needs (SEN) and they should have an Individual Education Programme (IEP). The IEP meeting may conclude that this area needs to be targeted. In that case, staff will plan how to encourage your child to interact with others, both in the classroom and in the playground.
At first, this may need to be closely structured, but as your child grows in confidence and builds friendships, so the need may lessen.
Differences between children
Remember, all children have individual personalities. Some children don't want to be always playing with others; they like time to themselves, or with one special friend. Children with sight problems are no different.
