I normally send DS to nursery in cheapish shoes as they often get ruined but last Thursday they went for a walk and DS jumped in alot of muddy puddles. Shoes needed cleaning and drying so the next day I sent him in his clarks shoes (with some wellies for the puddles!). MIL picked him up that afternoon and mentioned when I collected him that she couldnt get his shoes on. Well, they were the wrong ones but EXACTLY the same. He is an 8G these were a 7G. She said they were the only ones there but nursery old her a few kids had the same shoes. It is now wednesday and they have not been returned, (i returned those we had). If they don't turn up by Friday would it be unreasonable to ask nursery to email the parents asking them to check? Clarks are not cheap and whilst I am down a pair of shoes another child has a pair they can "grow into". WWYD?
