Handmade necklace on my doll

The lovely necklace that I first made for my mom is now on my pink Baby Wanna Walk doll. I still have this doll with me, can you believe it that I kept in the box for over 15 years. The still in good shape but I don't know if it still work if put on the battery.

My mom wear the necklace even in the shower, the handmade necklace by me is made of beads. My hobby is making jewellery but I don't it full time. I show my mom the doll and she remembers that I own this doll. Mom is getting old and she is forgetful, some things I mention she cannot remember at all. I even told her about my classmates but she cannot recall any of them.
