Rebecca- I had the same with aaron- the first three days he went back to work, when he came home Kaetlyn was really upset, and he was upset he couldnt play around with her, causse all she wanted to do was sleep- she cried.
Luckily he now has four days of to spend a lot of time with her (but then he is workin 7 days stright, so that is going to be abummer for me and him).

I must admit also that when aaron is at work, Kaetlyns nappy does not get changed as much- I just forget to do it, whereas aaron is more poractive in doing it as he cant feed her-its like its his job that he does for her
