MIL

I realised my MIL likes to take things from my house..so she saw this crystal stool that she likes and she wants to take it for her home I give to her..I bought alot of those magic white sponges and one day when I wanted to use I realised there are none and when I asked my husband about it he said his mother gradually took all the magic sponges. I have delivery tissue boxes and bought 8 rows of tissue boxes..she also want for her house and took 2 rows I give her..den I use this Swarovski pen for writing down my LO feeding schedule she took it without asking me. I also bought a big box of pain relief patches for my husband to relieve his aches from carrying baby. My mil also happily took a few packs within the box, come my house use loose packs too. Should I voice up or just let it slide since she is my MIL?
