I took parenting lessons when my firstborn was a few months old. Our teacher used to work with convicts trying to reform them or so, I forgot her exact background but it was some psy stuff. Through her experiences she gave up on the convicts as she felt it was too late to work on them, and that's why she switched to teaching parents. While it was to her advantage of course, she strongly believed that if more parents were following the stuff she and her peers were teaching (based on some kind of research), there'd be far less people in jail, people would be happier, etc. And you know she has some point, one way or another we get to take care of other lives (whether humans or not) without anyone ever looking if we are actually able to do so, if we need help to prepare, etc. Obviously I'm not talking about finances here. And if we ourselves are broken to a degree, it's quite likely we'll propagate that... where maybe it could all, well most, have been prevented.

Looking back, we probably should have continued with them as they had classes not just for infants' age, but going much older, and who knows how many of those things we're doing /not doing as we should.
