Mom obviously only cares about herself if she says no to SM doing/being...
Why is this the standard answer?
This seems to be the go to answer for some SM's who seem to think that moms don't have a clue or are just selfish bints instead of looking at things like "if the parent is stressed it can stress out the kid more" or maybe the kid knows mom and SM dont' get along and don't realize that mom isnt' going to leave her kids side for SM to be there, which can cause stress (this is from the hospital post).
When it comes to school and mom doesn't want SM involved this same line is said (in different variations).
But unless mom is explaining herself to SM (and I doubt many do), many Sms are assuming they know moms motives for saying to to the nonparents involvement. Why is it seen as such a horrid thing for moms to decide that SMs can't be involved in certain areas of their kids lives, despite what a SM or child thinks is best in those certain situations?
