AIBU to make DD pay for replacement PE kit?

[RainbowSparkles]

DD1 (12) has lost half of her PE kit, replacing it will cost approximately £50.

Parent A wants DD to pay for the replacement kit as they have lost equipment over the year which parents have paid replace and DD was told she would need to pay to replace the next thing that she lost.

Parent B doesn't want DD to pay to replace these items as they say we don't know if the items still fit DD and we probably would've been replacing them anyway.

Would Parent A be unreasonable to make DD pay to replace the items?

Harsh but you shouldn’t have threatened her with having to pay.
If her school is anything like ours the changing time is rushed and the kids leave open games bags all over the floor and as identical things get mixed up. My kids have come home with different games tops, socks, shirts, even one school shoe! I always wash and return but it is possible to not realise what you are washing does not actually belong to your child unless checking name tapes each time.
Also schools absorb stuff! One y11 boy was given his cricket trousers he lost in Y4!!

A 12 year old should know better really. I don’t expect my 9 year old to misplace his belongings so definitely wouldn’t expect a 12 year old to. I would make them pay for it too and hopefully they won’t lose it again.

If you think it's in lost property at school why not go there and look?
