Was in the supermarket with my 22 month old. He was hysterically laughing in a fake laugh for most of the shopping trip and i was laughing at him as it was a funny laugh i hadnt Heard him do before. I’ve since realised I think he was laughing at people in their masks but at the time I didn’t piece it together. Anyway he laughed at a little girl, she turned to her mum and said ‘mummy that little boy laughed at me’ in a really over the top whiny voice. To which the mum replied ‘it’s okay darling, some children don’t have manners, the little boys mummy should have told him off’ i just Walked off as i hate Confrontation but it’s playing on my mind. The girl was in school uniform so was at least 4/5. I don’t think me or my son did anything wrong. I’m not going to tell him off for laughing and having fun. Obviously when he’s older i would Tell him off straight away if he’s knowingly laughing at people to be hurtful. But he’s 22 months old and at that age everything is funny. AIBU?
