Is making a list rude

My 9 month old has never stayed with anyone besides me. I’m thinking a nice list for my mom who is keeping her tomorrow for at most 2-3 hours. Now my mom has always watched the other kids ( my siblings kid) but I’m like 😬 because I don’t like being away. I just have something to do and can’t take baby I’m just like man what if this or this. Would a list be rude of like her likes,dislikes, what her moods could mean, how she like to sleep, what it mean when she wants her milk but sometimes she will want her milk but will push it out and take a break for a sec and that don’t mean she done. Or would this be offense. my nerves are so bad I literally have backed 3 bags a toy bag, a bag with her favorite books and the diaper bag.
