Hi everyone. I have a 3 year old (3 years and 2 months) he's been going to childcare since he was 10 months. I've got no concerns over anything else apart from he doesn't like playing with other children. He's been going to a playgroup for 1 year and doesn't often play with the other children. He prefers to play alone. He started nursery school at the end of September. He loves going and talks about the other kids there and tells me about his best friend. However in the playground he won't let go of my hand untill it's time to go in. He said he's scared. A child tried to hand him a toy and he just ignored the child. Just wondering if I should be concerned? Thank you for reading
