This parenting lark is a complex business. so is the definition of a "good" parent. The idea of being able to say that it is never possible to be a Good Parent (ergo you are a Bad Parent) because of one aspect of your parenting/behaviour is, imo laughable.
is it possible to be a good parent and take drugs?
is it possible to be a good parent and break the law?
is it possible to be a good parent and get shit-faced once a week?
is it possible to be a good parent and eat meat? have plastic toys? shop at Asda? abuse apostrophes?
imho to say an unqualified "no" to any of these is ridiculous. it's shallow and somewhat lacking in the solidarity that parents could do with. It can also come across as a tad arrogant.
glad I got that off my chest.
