T.S.
Real quickly--I think part-time work is the best solution.
Full-time leaves you exhausted, and sometimes feeling guilty, and SAHMoms have I'm-the-maid-around-here and lonliness issues. (generally speaking, doesn't apply to all)
It's important to have recent work experience in case you need it, and it provides adult time and outside of the home feelings of productivity. Hope it works out!!
