I love my aunt to pieces but even before my baby was born she kept mentioning babysitting and now that she’s getting bigger she mentions it more often and I try to tell her that my baby won’t let anyone keep her like it’s gotten harder for my mom to even keep her (she absolutely loves my mom. Even says “nana” all day wanting to see her) from where she’s so attached to me. I just don’t know how to make her understand that my baby is a big mommas girl and doesn’t go anywhere without me. 😫
