DS is 4 and in reception year. After about three weeks into Autumn term teacher said he was not settling - she said he was one of the more immature memebrs of group and could be a little silly. She also said he was bright and enquisative and asked a lot of questions without putting his hand up. He then seemed to settle and was doing really well. However, has been really unsettled suddenly for about the last month. She has written several notes in home school book about bad behaviour (fairly minor incidents but lots of them). I always follow up with discipline at home - have now removed a batch of loved toys and put them into cellar as was taken aside yet again - she said his behaviour has been 'manic and grumpy' this week. Don't know how to help him as he is delightful most of the time at home. Recent notes said he has 'hurt' a few other children and he is wetting himself almost daily at school. I am getting EXTREMELY upset as this is not like him - he has always been really gentle don't recall him every being aggressive or overly grumpy.He is actually a really gentle 'sunny' and loving boy but he is very sensitive think he may be anxious. Any advice? Any reception teachers out there? Thanks!
