The main difference between a stay at home dad and a stay at home mom is anatomical. Everything is for the most part the same. Stay at home dads and stay at home moms do the same thing. They deal with their kids in mainly the same way. They have to do the same errands. They have to prepare food. They have to get school supplies, etc., etc. The main differences come really externally, not internally. Stay at home dads and stay at home moms are perceived differently by society. But inside and at home, they all do the same things so it´s just body parts.
