Sorry, but this is crap. And yes, of course I have an axe to grind, of course I'm a working mother whose children have been in f/t childcare since the age of 6 months, and of course that invalidates my reaction to this... but hey, I don't care, I'm going to post it anyway.
I have two dds. DD1 is in Year 1. She was in full-time nursery care from 6 months to age 3. Then she was in a state nursery school mornings and with a childminder afternoons till she started 'proper' school. She is certainly not badly behaved. She has some problems concentrating and could listen to the teachers better. It may be that if she'd been with me till she was 5 that would have been better, I don't know. But I know that she's not having any problems at school, so she can't be that bad. DD2 was at nursery from 6-18 months, then with a childminder full-time till she started part-time nursery (which is where she still is). She is one of the best-behaved children in the class (proud mummy emoticon!) and is always coming home with stickers for being helpful, sitting nicely, or whatever. Is this because she's with a childminder (and therefore something approximating more closely to a home environment)? Or is it just her personality?
It makes me really angry to feel that teachers are judging parents on the basis of decisions which they make for the good of their families. Grrrr...
(Oh, and btw, I didn't click on this thread because I was looking for a fight! I do teach, but I teach over-18s and, guess what, no, I can't tell which of them were in childcare and which were not!!)
