I’m use to being a mother of two boys but I’m having my first little girl in July and when I use to lotion my boys after their baths I’d lotion their private part as well but with a little girl I’m not sure if that would be the right thing to do I dont know if I should lotion her vagina or not because I don’t know if the lotion will irritate her or not what did you moms do?
