I think that under the circumstances, he is probably going to need those cuddles to help him adjust as well. I don't think that in a single day you changed their baby, but I think that he is probably just one of those babies that needs lots of cuddles kwim? I think that to help you through this time that you are going to have to do what makes things easier for you, and that may mean you spend a lot of time holding him. I posted in your other thread that you should get a carrier for him to make it easier for you to go about your day to day as well.
