Maybe try asking some of the other parents if the clothing happened to accidentally go home with them. My daughter has been going to child care at her preschool, which is available after preschool in the morning, and is a different room in the same building. 2 weeks ago a jacket of hers went missing - she has a locker for her preschool class, a locker for child care (none of the lockers actually have locks on them), and there is a few lost and found bins in various locations. We checked everywhere, including other kids lockers and haven't found it yet. I am wondering if it went home with another kid by accident so I left a note by the sign-out sheet in the child care room for other parents to read, asking them if they would not mind checking their kids backpack for it, just in case it's stuffed in there. It's got our last name written on the tag too so it's not like someone can't know that it's not theirs if they happened to notice. I know how you feel, like it shouldn't be that big of a deal, but when it's something nice that you spent some money on, or it's a gift from someone or something your child is especially fond of, you want it back - it's the principle of the thing. If you don't have any luck with the other parents, then bring it up with the daycare provider again, and ask her to please take a look for it NOW if she wouldn't mind. Or leave her a note somewhere so she can "remember" better.
