I thought being naughty was what being 2 years old was all about!!!
What is the teacher on, saying that you should scold him more if your maid had just said that he listened at home? Why would she think you'd need to scold a kid who was good at home?
If he's naughty at school then it's up to the teacher to tell him off there and then - 2 year olds won't remember by the time they've got home what it was they did that was supposed to be naughty, so there's no point in expecting you to tell him off 2 or 3 hours after the event is there?
It depends what he was supposed to have done to be considered naughty in the first place - was he just running around when he was supposed to be sitting still - or was it something more serious like flooding the bathroom?
I found out that my 3 year old was made to stand facing the wall on her first week at kindergarten. When I spoke to the teacher about it, I gathered that it was because she'd kept getting up to play with toys when the teacher wanted them all to sit down and listen to her.
I think kids in Singapore are expected to behave like they're in a proper school environment from an earlier age, which is fine if your child knows that's what's required of them, but if, like me, you come from a country where they're just allowed to do what they want at playgroup, they find it difficult at first.
My daughter is OK now though, I think she's sussed that she's not allowed to just run riot at school anymore!
