The first time I gave my first baby a bath, I couldn't believe they hadn't sent us home with more directions for how on earth we were supposed to actually get this tiny squiggling six-pound bundle clean. We were still in that phase of being utterly terrified of hurting her, so she might have gone quite a while between baths in those early weeks. Thankfully, babies don't need to be bathed very often, but you'll want to look out for these signs your baby needs to be bathed more often, because it can be hard to tell.
If your baby is constantly smelly from spit up or any one of their many bodily fluids, or they really dislike the bath because they don't get in often enough, you might want to increase the frequency of your baby's bath time. The Mayo Clinic recommended bathing your baby three times a week during those early months, and more once they are mobile. And actually, less is more. Most people actually bathe their kids too often, which can actually dry out the baby's skin and lead to eczema, according to Parents Magazine.
So while it's less likely that you're bathing your baby too infrequently (as opposed to to often), if you notice these signs, you might want to get that baby in the tub a little more often.
