M.C.
I know that you are feeling stressed out and anxious right now. I think that you shouldn't make any hard decisions until once the baby comes home. A baby can strengthen many strained relationships. I agree with the post about trying to rent an apartment or hotel suite. If you live in the Fairfax, va area there is one hotel near Fair Lakes that are 'suites' and rent on a weekly/monthly basis. All the ammenities of home. That would give them an opportunity for a break from the family and always having to feel the hostess. As for the length of time that they are staying, again wait until the baby comes home to make a decision. There will be a time when you will pray for someone to watch the baby for an hour or so so that you can get some much needed rest.
Good luck and take it one day at a time.
