If your sister did to your baby how would you feel? Would you feel it is pretty heartless of her?

My sister gifted my newborn baby this baby musical merry go round ornament and just recently because we had a falling out while I wasn't home she has gone into my room and she has taken the musical ornament back.

Update: She is now demanding everything back that she gave as a gift to my baby. This woman has kids of her own and I have never once in my life ever taken back anything I have ever gifted them.
