hi there just been through this. Our kids are the same ages hehe. The first thing I did was when I had the baby and he came to visit in hospital he brought her a prezzie and the 'baby' bought him one also he really loved that I just bought one of those kzone magazines worked a treat because he was really busy with that for ages. I have tried to involve him wherever possible so i will say lets go give her a bath or pick some clothes out for bub, bub is crying go choose a toy to make her happy etc. When I have to sit down and feed bubs I tried having something new for him to play with like a puzzle or playdough or craft. At the moment though he wants to go potty everytime im halfway though think it his way of showing hes figured out what im trying to do lololol. I also been trying to get out to the park and make him tired so we can all have a midday sleep works a treat.

I have to tell you this is the exact thing i spent so much time worrying about and i learnt kids are so resilient and can take almost anything in stride, she will impress ypu
