admylin Yes, that's exactly it - DD1 is also very well-behaved (at school, at any rate...), one of the best in the class, but children just don't seem to get praised here. At the last parents' evening we were only with her teacher for about a minute as she said she didn't have anything to say about her! Instead, she ended up telling us about the one badly behaved boy in the class. 
Canella I couldn't do without my morning caffeine kick! (Actually I think it's more psychological than anything.) That's sad about the teacher being harsh to your DS's best friend; so many teachers don't seem to make allowances for any child who doesn't quite fit in and just focus on the negatives.
hupa Yes, I do have some stickers that I bought for the English classes somewhere and then didn't get round to using them - and a sticker book for each child too - I really must dig them out.
Your teacher sounds lovely. I'm sure there are very positive teachers here too and that I'm no doubt over-generalising; it's just that we've had quite old-fashioned teachers so far with fairly old-fashioned ways of teaching. DD1's first teacher retired at the end of her second year, her second is retiring next year and DD's teacher is in her late fifties so they've all been of the same, fairly strict generation.
Went ice skating again this afternoon but poor DS's new skates were far too big for him so he was struggling to stay upright. We really should have tried them on before the lesson; I didn't even check that they were adjusted to the smallest size (they're 31-34, and he's only just size 30). If the worst comes to the worst, we'll have to hire skates at the rink next week - that'll be ?30 down the drain on the skates!
Oh, and I got told off by an Oma because DS only had thin socks on when he was ice skating. (But he had trousers and ski trousers on top, so at least there wasn't the dreaded gap!) Have just asked the DC whether their feet get cold when they're ice skating (mine don't and I get cold very easily). The DDs said no, but DS said his were (although he's never complained before). Even so, grrr... what makes her think it was any of her business. I suppose I got off lightly as at least she didn't tell me he would catch cold.
Talking of which, about half of his KiGa group are off sick - there were only 11 there yesterday, so we got lots of the Gesunde Jause food back. I am just amazed at how DS has managed to avoid coming down with anything so far; he regularly refuses to put his coat on between KiGa and the car, frequently goes out without a hat and ice skates in thin socks. Oh, I forgot - he's hardened.
