Mummy’s of little girls I need some advice!

Just after a bit of advice on how you keep your girlies fresh and clean 🧽 down below. I notice every now and then, happening more often that when I change my 3 year olds nappy she has a bit of an odour down there. Some of it will probably be urine I imagine but it doesn’t go when I wipe her down or anything. She gets bathed every other day ( as in a bath one night, no bath next, then bath the next night) so I’m it’s not like she isn’t being cleaned properly or enough, we use her flannel and give her a decent scrub down below while she’s in bath (she’s sat down in the water with her legs crossed, so it’s easy enough to give her a good wash). But is this enough? Should I be putting the flannel further up and scrubbing harder like I would mine? Might seem like a stupid question lol. I already have a 5 year old daughter and I don’t remember her having a certain smell like this. So not sure what I’m doing wrong this time around 🙈 should also mention she hasn’t complained saying it’s sort or itchy down there, it’s literally just a slight odour that seems to be coming from her... any advice on products or different ways to try clean would be much appreciated ☺️
