How much trouble is it to put an apron on?! AIBU

[OnePlusBun]

AIBU to get annoyed every time DD comes home from nursery with clothes covered in paint? Not annoyed at DD. At the staff.
I've jokingly said a couple of times "didn't you wear an apron when you did your painting?" and the staff say Oh they do wear aprons. I know they don't because they take pictures for the parent portal and I've only ever seen DD in an apron once!
Her nursery clothes are only cheap - primark, supermarket, etc but several times the first time she has worn a tshirt it has been ruined because it's covered in paint that won't wash out (on a 60 wash with stain remover)
Should I ask them to put an apron on (not in a jokingly manner) or just face facts that nursery clothes get messy and just send her in wearing the paint stained clothes?

For preschool my dd had 5 tshirts and 4 pairs of trousers which she wore (attended 5 mornings). By the end of the year they had pen and paint marks on (although hanging outside to dry after a cool wash with stain remover got most of them out - even in winter). I only get rid of clothes that had food (or worse) stains. Everything else is for playing in the garden until trashed. It can be clean but with marks from paint etc. In an ideal world they would wear aprons but as pointed out up thread it's not always possible and I'd rather they focused on my child having fun and being safe

My DS goes to a childminder - they often do painting and he has never once in 18 months come home with a single paint mark on either him or his clothes. I have no idea how she manages this and I can only chalk it up with other miracles like the fact he eats everything and naps like clockwork with her.

You want cheap clothes to stay clean and tidy v. your child having fun and enjoying life whilst developing valuable skills and learning. Is it really a question?

YABU. Let the nursery staff spend time encouraging the children and developing their creativity rather than fighting children in to aprons.
