Ds is in nursery, and the whole school is dressing up as either Wally or Wanda for World Book Day, Ds doesn't want to (he wants to dress up as the dog from Room on the Broom), he's never "read" the where's wally books although he has a wide collection of books and is read to every night which he really enjoys. We've shown him the costume, told him his friends will be dressing up too and he is adamant that he doesn't want to. AIBU to not force him to wear it? We have nothing suitable to make one so it will mean going and buying things. I don't really want to have a massive power struggle on something that in my opinion doesn't matter.
