My son (3.5) has recently started to take extra toys to the playground or sandpit (little diggers or trucks etc) to share with other children. It's quite a turnaround from a few months ago when he was so possessive about anyone so much as touching his things. He's an only child and loves playing with other children and I think it's his way of trying to make friends.
Today, at the playground he shared his digger with another boy but when we were leaving he wanted to give the boy his digger to keep. He got really upset and was crying when I explained he might be sad if we never got it back and that we don't really give away our toys to strangers.
Just got me worried that this is not normal behaviour. Anyone experienced this?
