My 2 stepdaughters have moved in with me, DP and our 2 DS. They moved here 3 months ago and also moved schools to one nearer us. Youngest stepdaughters teacher is getting on my nerves. Every time she comes home from school the teacher has changed her hairstyle, at least 5 times I've sent her to school with ponytail/pigtails and she comes home with a plait instead and says "Miss did it". Also, she is a really picky eater and we are finding mealtimes really difficult at the moment, one thing she will eat is ham sandwiches so she has packed lunch for school. For the last week she's come home and said that she hasn't been eating any of her ham, "Miss" has been taking it out of the bread for her and throwing it away and she puts crisps inside instead. Why does she feel the need to do these things?! AIBU to let it get to me?
