haven’t had a kid, but 2 weeks with a wife who has chronic fatigue seems really short. honestly the start up life doesn’t strike me as great for having a kid, but idk what your job situation is. can you peace out for a day or two every week without things going off the rails? if so, you might be fine. but usually, start ups are pretty lean, and rely pretty consistently on the presence of each person on the team (or at least, this is what i’ve heard, i haven’t done a start up, either)
how much do you have to help your wife? have you asked her thoughts on the situation? does she work?
you’d might want to do some research on child development to help form some timelines. e.g. when does the baby start crawling around / how long are they breastfed? learning stuff like this should help you roughly forecast how much supervision you’ll need to give (it’s probably not linear, fwiw)
last thing to consider is, what if your wife or baby comes out of this requiring more care than average? what benefits does your work provide in those situations? not everything goes as planned, and i’d be a little worried about that given your wife already has one chronic condition. pregnancy is not exactly easy on a body
regardless, i hope you can figure things out and everything works out well for you and your family!
to clarify, i’m talking about the hypothetical situation where OP’s wife, who has chronic fatigue, also has a baby. i’m sure there are people out there with chronic fatigue who have had babies, of course, and they are champs, but uh, i believe that would be a future situation for OP :)
