@katrina2017 Most resources say children before puberty only need to bathe 1-3 times a week, and it's better for their skin and hair to not be washed daily. They do clarify that if your child is specifically dirty, oily, has been in water (lake/chlorine, etc.), or has bug spray or sunscreen on, that you should bathe them in these circumstances.
Personally, I do a daily wipe down of all my kids (6, 2, and 5 months), but we only do a guaranteed bath 1x a week. We do extra baths if they request one as an activity/play time, or if any if the other circumstances require it, but we often have just one a week if they're not specifically dirty or smelly.
I don't have any issues with smells or rashes or anything for my 2 kiddos in diapers. If there's a poop blowout though, that warrants a bath. Everything else seems perfectly fine with a daily wipe down and using diaper cream.
