Is it okay for someone who doesn’t shower to carry your baby

Is it okay for someone who doesn’t shower to hold your baby even if there part of your family my husband doesn’t like my grandma to carry my 3 month old because my grandma doesn’t brush her teeth and hasn’t showered in a year like she doesn’t like taking showers I guess and her room is always dirty she drives and everything it’s not that she is not able to shower I don’t know how to tell her in a nice way to be more clean with herself I just let her be if she doesn’t want to shower but sometimes she stinks really bad even my husband could notice she only brushes her teeth when she has to go to the doctor like she has like two different personalities when she’s okay she is nice to me when she’s not she calls me a slut and a lot of stuff she raised me but now she changed a lot because of two of my aunts that have always been jealous of me she got separated from my grandpa a long time ago so my husband tells me that maybe her and my aunts are just jealous because she doesn’t have a man like people don’t really know how she actually is because she shows a different face to family like if I told my mom or family that she doesn’t shower at all or even wash her her I know they wouldn’t believe me and think I’m lying that’s why when she carries the baby I always take the baby a shower she doesn’t even like my husband because she wants to be right on everything sometimes when me and my husband are talking she stands in the kitchen Pretending to be doing something to be hearing what we are talking about
