Rodziny wychowawczo niewydolne?

i know this means families incapable of properly rearing their kids but is there a nice.neat English term for it? Educaitonally nreglctred might be OK, except the next sentence talks about children negelcting their school obligation.

Educationally neglected ! Narr that doesn't work.

If you are trying to describe a Mother who doesn't send her kid's to school or look after them properly then I would class her a ( lazy cow ) with an insult about her added for good measure, maybe she gets drunk or has men in her house all day.

Useless cow !

I finally settled for dysfunctional -- that' s convenient catch 22!
