Hi. Can you both not go IP at the same time? If you have kids, can they not stay with grandparents, aunts, uncles, cousins etc for a short while?
Sounds like you both need pretty intensive help right now. Why is your pdoc unavailable? Is there not an emergency, fill-in pdoc that you can go to? Surely your pdoc has a contingency plan in place for people such as yourself in crisis situations. Ask/tell his receptionist. She may be able to suggest something.
