i think part of it is attitude. on both sides.

whining that someone can't rp or chat online with you much because they have a kid to focus on is a really bad look.

but similarly if someone's saying that since they're a mother now they don't have time to waste on immature online hobbies, they shouldn't be surprised when people who enjoy those hobbies pull away. you can choose to prioritise other things (and should, if parenthood is one of them!) without denigrating the stuff you used to do. all in the phrasing.

i like hearing people's parenting stories though, because i like kids but don't have any of my own.
