My wife stays at home to help raise our kids, do you have a wife?
I have a housewife, A housewife is a woman whose occupation is running or managing her family's home. So just like yours probably.
Yeah we have two little girls that my wife home school.  What does your wife enjoy doing? 
She like knitting at home and cooking. We are about to have a kid so I guess she will then be a "stay-at-home mother".
Yeah you can say that then,  what does your wife like to cook?
I like spaghetti so we have that a lot. She also makes some mean breakfast. Webster says a married woman who is in charge of her household. But I think it is more a mutal thing.
