My wife and I have an infant who spends much time on the floor. For hygienic reasons we have decided to remove our shoes at the door and generally walk around the house in socks. We ask our guests to remove their shoes at the door as well. My father has objected to this and informed me that Jewish law restricts us to only remove shoes in a house of mourning. Is it true that we must wear shoes or slippers when in the home?

You should make every effort to respect your father. There is such a custom, but one is not obliged to follow by it. Rabbi Binyamin Bamberger
