This is spurred on by another threat about someone struggling to keep their house clean. They mentioned that their kids are bathed once a week. This caused a lot of negativity amongst posters, with some comments calling bathing your kids once a week 'neglect'. This surprised me!!
My DC is 4 and has on average 2 baths a week (and yes, sometimes that means 1 a week). It has never been part of our bedtime routine - it gets them het up rather than calming them down. Their hair is washed once a week in term time after swimming class (v long hair as per DC's request, which takes an age to wash and dry). On holidays we once went 3 weeks without washing their hair. Hair was not smelly and looked lovely throughout.
My DC is not smelly, not dirty and most definitely not neglected! They have clean clothes, tidy brushed hair, are very popular at school, and have a generally nice life. (They also have a miraculous ability to somehow stay clean even when eating bowls of bolognaise and poking around in the dirt at school, which is helpful 🙏. Obviously if/when they do actually get covered in mud I wash them!).
I did some poking around and the American Academy of Dermatology say that children below pre-teens do not need more than 1-2 baths a week as long as they're not actively dirty/smelly.

So is it really that bad not to bathe your children very often?
YABU - Children are dirty and sticky, more washing please!
YANBU - As long as they're not stinking up the bus then it's fine.
