Hello, first post! Ds (2) goes to nursery with the ds (also 2) of our bst friends.. they are almost like brothers, having spent loads of time together since birth. Friends' ds much more boistrous than ds, and has bitten on several occasions. Time out done at nursery re this, but what should I do? I'm going to talk to my friend about it but short of stopping them playing together is there anything we can actually do to stop it? My ds v upset by this. Thanks for any help or advice!
