Not sure if scared is the right word but anyway.
DS is 3. He has always been a quiet but lovely boy. Rarely tantrums, not into rough playing or anything like that. Prefers to draw or quietly play with his toys. Everything must be organised and in his order and can’t be messed up.
I have tried since he was tiny to socialise him but even as a small baby he would hide and cling to me at all times. I’ve done activities, soft play, play dates and sent him to a lovely childminder and still he is extremely reserved.
He wont speak to new children very easily and is very shy. He hates shouting and loud playing by the others and will burst into tears and hide with the nearest adult. If a child speaks to him he won’t speak back.
If an adult speaks to him he won’t say a word but is actually very fluent at home.
He is also scared of new experiences, new places, for example he spent a week crying about pigs because one snorted at the farm and he didn’t like it 
Anyone else got a child like this, where am I going wrong?!
