Does any one else go by mom?

I'm afab and use he/they pronouns but I've got 2 kids. I let my kids call me mom, because honestly to me mom is just a concept. I am mom and I do the mom things, they don't care what my pronouns are just that I'm here. But recently I keep being told it doesn't make sense because moms are women, they use she/her and that they don't know how to refer to me. Does anyone else also go by mom/dad despite their pronouns maybe being seen as "wrong" to that title?
