My DD is 4 and in Reception. Every morning one of her friends brings her in a sticker. DD has come home upset saying the teacher shouted at them and snatched the sticker off DD and ripped it into two. She has said her other friend wanted it too so maybe was jealous so teacher took it off them. But shes now really upset that it was ripped. I know it’s just a sticker but she was excited to have another one brought for her by her friend when I dropped her off this morning and she’s upset she was shouted at. Was it wrong of the teacher ?
