ah bum babe! i am sorry to read this, it must be so hard . there is a mum at MG that is going through similar things. her DS seems to really resent his new little sister. and when he is not actively trying to hurt her, he doesnt acknowledge her ITMS. it is tearing his mum up. i guess the best is that he will grow out of it and learn that she can also be heaps and heaps of fun .
and remember DD wont be little for long :wink: she'll hold her own soon enough and will be able to win him over. FWIW my mum and one of her brothers had a similar situation and they ended up (and continue to be!) incredibly close.

babe xx
