Am I right or wrong?

I have a Storage Tote and I have been collecting baby stuff for when I have a baby.

My mom was going to this baby shower of her friends and she asked me if she can take 1 thing with her to the Baby Shower and will pay me back. So I said ok. Instead she took 6 things with her to the baby shower and she says she don't owe me a thing at all. That Friend and her don't even talk at all.

I just want her to replace what she took from me or atleast give me back what she owes me. Am I wrong? Honestly.

Update: When I talk to her about it, it just turns into an argument. So I've decided that when she ask me If she can borrow some money ill remind her of her dept and I can't give her a cent til she pays me back.
