I raised 9 kids, and when my oldest was 12 (and before and while the youngest 3 were born) I went back to school to earn my degree and then went out to work full time.
The older kids, who were raised by me as a stay at home mom, and the younger ones, who went to day care while I worked, all turned out OK.
Zedushka had to take the little ones to day care since he started work later than I did, and so he had to deal with getting them out of bed and dressed and fed in the morning.
