Disclaimer: I have posted about this before (when I thought it was a one off) but now it has happened again I don't know if I should do something?
ExDH took DC to DBiL for Christmas. We have two DD primary school age but think upper years. When the girls got back they told me this happened (I asked ExDH and he confirmed it).
I bought all the Christmas presents, and included in the girls' stockings a box each of trashy American breakfast cereal that they always ask for but are never allowed to eat usually. When the girls opened them DBiL wrote 'BAD' and 'Unhealthy' on the boxes and lectured them about the amount of sugar etc.
DBiL has form for this kind of behaviour. On a previous visit he made them do star jumps before they were allowed a piece of birthday cake. He only seems to do it where the girls are concerned (he didn't make the adults do star jumps or go around writing 'bad' on the adults chocolates or booze for example).
ExDH seems to think his brother's behaviour is totally acceptable and refuses to do anything about it. AIBU to worry that this is fat shaming and could lead to body issues/eating disorders?
FWIW I am overweight so I believe that's why DBiL behaves like this, but having struggled with weight my entire life, no one wants the girls to not become overweight more than me.
