God bless you both. My son-in-law stays home sometimes with one of my grand-daughters.
I am a stay at home dad as well. My wife's career was doing better than my own, so for the sake of the kids I decided to stay home full time.
I think stay at home dads are the key to true equality in the workforce. Most women I know recognize this, and applaud our lifestlye. Men are a bit suspicious, like "why does he get to stay home while I have to work these insane hours."
