We definitely don't expect and we would never ask for regular FT childcare from our parents. I'm also sure they would say no if we asked!
MIL retired two weeks ago and she eventually wants to watch our girls for one day a week (yay!!!) but she wants some time to herself first....totally understandable! Some of my friends are bewildered because they think we should ask MIL to watch the kids FT instead of paying for daycare.
