shrunkenhead, are you going to homeschool?
If not, do you feel sad that you'll no longer be raising your children when they go off to school and spend whole big chunks of their days without you, being raised by their teachers? :( :( And when they're a little older, don't let them take up sports or music after school! Because then you might not see them for seven or eight hours at a time, and then you'll surely have to accept that they're being raised by a random collection of teachers and coaches.
Because we all have to accept that "raising" a child certainly does NOT mean being the person(s) who is responsible for feeding them, clothing them, instilling values in them, planning for their future, deciding what food they should eat, deciding what's appropriate entertainment, what's appropriate discipline, advocating for their rights and needs, making health/school/life decisions for them, and making every major decision of your own life (including, if it's your decision at all, whether or not each parent should go out to work or stay at home) with the child's best interest at heart.
No, we'll just accept that what raising a child really means, is being the person who happens to spend the most consecutive hours with them on any given day. In which case, after you wave your last little darling off to school, I hope you can find a nice hobby to fill in the time when you used to be their mom
