My Ds is generally a well behaved child,obviously he's 3 and we get all the associated problems but nothing we can't hanlde, usually! However, over the last few weeks he has started hitting, kicking and biting his Dad. He hasn't done any of these things to me (yet!). DH is a very good Dad and DS normally has a very good relationship with him. Nothing has changed lately apart from the fact that I am pregnant (15 wks) but I can't really see this being an issue for DS at the minute. When he misbehaves with me I occasionaly smack him but only as a very last restort (his Dad never smacks him) I usually turn the TV of or take toys away etc and he generally stops.Please tell me this is just a phase and also what can we do about it in the mean time.
