My sister's toddler has epic tantrums. He will scream and scream and they ignore him so hopefully he will get over it soon. Today however we were at a soft play party and the play area is downstairs and I took both my kids to get a drink while she was with her son. He wanted to follow and she said she couldn't leave the table so he had a tantrum. It wasnt a long time or anything maybe 5 minutes but he just screeches really loud. When I came back (I didn't know he was having a tantrum) she was close to tears and started shouting at me as though it was all my fault. Then because I got annoyed at her she then said why am I so bothered about myself when she is the one who's stressed and having to deal with it and she started crying. AIBU to get annoyed at essentially getting blamed because her toddler was having a tantrum?? Several times she has expected my children to stop doing their normal things because he can't do it or because she doesn't want to help him do it because he has a tantrum.
