Sarah, I would definitely say that it is jealousy, and rebellion at not getting more of your time. I have heard it said that your older child "regresses" by about 6 months at the birth of a new sibling. I have found that not only did J go through this at the time T was born, he still does sometimes. And like Z, he picks and chooses as to whether he is a "big boy" or a "little boy" depending on what suits him at that point in time!!

The PPs have given you some good suggestions. I have used them all at various times. The thing that I have found works best however, is concentrated one on one time with him, and even talking about what is going on. "Mummy has to help T with this as he is a baby and can't do it by himself like you can. Soon he will be bigger and you can teach him how to do it himself. Would you like that?" sort of thing. Also, lots and lots of praise and attention when he does do things by himself. And just sometimes, doing things for him so that he doesn't feel too hard done by LOL!

GL with it hun. It is frustrating, but you are a great mum, and I know you will continue to find ways to ensure that Z feels loved.
