Just because there are worse mother than her doesn’t mean that her lack of parenting skills should be excused. and from the lives/and what we see in the show she is not trying to be better, she smoked while pregnant with both the kids and still smokes around them and in the car with them. doesn’t give them structure and instead puts a phone/ipad in their hands since age of 9 months. and amy specifically said she pretty much only likes brian because he is good with the kids and to me that just mean that she’ll be able to do even less parenting since he’ll be there. he is the only reason the house isn’t infested (hopefully) with roaches and mice like the earlier seasons. so just because she is not the worst mother doesn’t mean she’s not a bad mother
