I have had 4 c-sections and I don't want any visitors for a couple of months after the baby is born. So you might want to do it at your inlaws. Just take a bag of toys for your daughter or ask your mother in law to have some things there for her to play with. You could get things over there in stages, like drop off a diaper bag full of extra clothes, toys, diapers ect that stays at her house for when y'all visit.
Do you have an infant carrier car seat? He'll probably sleep in that the whole time. Babies don't mind sleeping in their carseat at all.
Make sure your trunk is cleaned out (husband's job) and bring home everything you can, but leave larger items you don't need right now with inlaws to pick up next time.
