Hello,
When I collected my 4 year old today the teacher said that he had been quite disobedient, not following requests etc. To be honest he is often like this at home, but an angel in Creche.
The more worrying thing she said was he said to a little girl at the tea table that he would "rip her head off". This is never the kind of phrase DH or I would use (and definitely not in front of him).
The teacher said she is only telling me because it is so uncharacteristic. Nothing unusual happened at the weekend, in fact we had a lovely weekend.
My SIL is a teacher, suggested he himself might be getting bullied, he is a very sensitive child or maybe he is bored. She said she wouldn't be too concerned about this feedback once.
