re: thoughts on stay at home spouse?

I "tolerate" my stay at home wife. I have a 3 year old son and one on the way. It really is a blessing for her to stay at home...as others have pointed out, there isn't anybody who can take care of/raise a child like his own mother can. It's very important during their early developmental years, IMO. Also, the house is always clean, dinner ready when I get home every night, laundry done, errands done, etc.

Honestly, I haven't had to set any expectations because my wife was a teacher, and being around and teaching kids comes naturally to her. She is also smart enough to know how to live on less than my income, so we've never really had to discuss spending habits.

As far as income needed, it all depends on your monthly expenses.
