Annie- I bet your kids look back now and were glad that you were at home with them too. Personally I think kids get more from a parent being at home with them, although I know that's not always possible. My brother goes on about how my sister has wasted her education (she's a clever lady, and has her degree and a doctorate) because she has never worked in her field of expertise, and indeed only started working part time last year for the first time in 12 years. But, she has 4 happy well adjusted daughters who may not have every toy they want, or expensive holidays but they have had a fantastic upbringing. And she's done what she wanted with her life, so maybe she hasn't made some great discovery in the field of animal nutrition, but so what?
