OP, it feels like you are being demonised, and I am sorry for that.
You asked a question and you got a mixture of responses - from a mixture of people with a mixture of qualifications and experience. The YABUs are, however, the most vocal.
You won't change the minds of those who are slating your actions...and they won't change yours, so it has ceased to be a worthwhile debate IMHO.
However, you are comfortable with your actions, as sanctioned by your GP, and so have no need to convince anyone else of their worth. Nor anyone else you.
We all parent differently. That doesn't make one of us better than another - just different. I, for example, am as good a mum as the next...but I am terrible at ensuring DCs' toenails are cut as regularly as they probably should be (yes, yes, they might get deformed feet or something and I'll be to blame). And we all have different opinions. For example (another one), I did give DCs Medised very occasionally when they were small...and on balance probably would do now even if my DC was below six, if I felt would he/she would benefit from it, but I understand that others might disapprove.
And in return, if I'm honest, I question the judgement of the parents I know who think they are somehow doing their DC a favour by not giving paracetamol or ibuprofen to them when they are ill (talking plain old Calpol, Nurofen etc now). I ask myself, " why would anyone deliberately make their DC suffer more than necessary?" It seems to be a rather cruel principle to me. But I accept that is only my opinion. And that each of our oinions are probably reasonably valid, because we are not talking extremes, abuse or neglect here.
