My shy 4 year old son has a v. competitive friend and while this sometimes pushes him on in a positive way, it sometimes pushes him over the edge! She's just joined his football lessons and he ended up in tears as she had scored more goals than him! Her mum and I are great friends and don't want to cause friction, or take away his only proper friend, but what can I do? I feel it could be eating away at his confidence.
