He will if he wants to continue living. I'll obviously do more of it while I'm home from work, but things will be much more shared once we're both back to work.
H plans on it, but we don't have a set plan yet. I imagine we are both going to be very very tired. I am such a light sleeper and wake up with any noise. H is a deep sleeper and I have to nudge him to get up in the am or when our dog was a puppy and it was his turn. By that point, I'm already up and have a hard time getting back to sleep. I have heard from friends that we will be so tired I will probably sleep deeper. I hope that is true, but we will see!
with DS, I had a horrible c/s recovery so he did it all for the first week (we do formula because of a medication I'm on) and then we went to half and half feedings with me doing a bit more once he went back to work (I have a flexible work schedule and work from home a lot)
