Do your kids call you "mom" / "dad"?

Interesting that she's making a change after 2 years! I'm 3 years in so I feel like we're pretty set in our ways. I definitely agree with not forcing them to use terms they're not comfortable with and that was my theory behind not steering him in one direction. The reason I brought this up is from an attachment standpoint, would using familial words help form the familial feelings.
