Have you ever come across a family where you thought it would be better for the kids to be raised by caregivers in a daycare than to be with their stay-at-home mom?
Unless the stay home mom is an ill-tempered out of control verbally and physically abusive psychologically upset woman, no. I don't think anyone can give the unconditional love, time, care, energy and values to a child than the mother.
In cases where the mother isn't a stay home mom, obviously daycares/other are the way to go.
