Oh Mel honey, for you, I had that same concern,when I got preggers again, but I kept reassuring Nyah that when baby comes she's have to help alot, like feed baby, put baby to sleep bath baby, change baby, all that you do involve him in it to, although he wont be able to physically do these things it really helps to tell him "OMG Jackob do you realise you just helped mummy get baby to bed,slepp,bath whatever", make a hugh deal out of it and smile while you say it, well that's what I did and it really worked. Also let him sing to baby while in your tummy or talk, let him touch your belly at all times even if you dont feel like it,I was sick for 26 weeks day and night and had really bad anxiety all the way through as well as my depression-fun not!, but seeing Nyah and having her rub my back in the shower while I threw up or having her tell William in my tummy that she was his big sister and she loved him (didnt know the sex then), really got her involved-sorry so long darl.

I think you'll do fine, maybe with his sleeping do you think that he senses your anxiety about this??
