There are other alternatives to Daycare. And children tend to be in school most of the day. I have a sister who is going to be a teacher so that when she does have a family she will be home.
That's why more women go into the teaching profession.
"No kidding?" asks the ed major. Most children don't go to school full time until they are about 6 years old. Teachers work at least 180 days of each of those years AND many places (if not most) require a Masters degree within 10 years of hire. That does not equate to being home.
Day care is not the worst thing we can do to our children. However, I wouldn't deliberately structure my life so that my babies had to be in day care. I would advise any daughters of mine to think VERY carefully of what kind of life they want to have. If they want children and a home life, going to med school would be counterproductive.
