just let her. you get to have a break baby gets fresh air mil get to bond with baby as well. At that age, maybe ur mil got back pain and cant carry baby well but wants too maybe thats why
Maybe it's a hassle for your MIL to push a pram. Whatever is comfortable for her, let her be. As long as your baby is fine and safe when your baby is with her 😊
Uhhh my parents babywear my kids.. i have no issues with that..
