Ds (in Reception) has just told me in a sad and worried tone that he took his trousers off at playtime. When I asked him why he did it, he said that another boy told him to and that the boy kept saying it and this other boy also took his trousers off.
Apparently he was punished - had to miss playime.
Bearing in mind that childrens' accounts are not always reliable, is this just normal playground playing or should I be concerned?
