Bathed nightly after dinner. We do BLW so if I didn't bath DD (1) she'd be going to bed covered in food.
If we're coming home late from a dinner out or something, I generally pack her pjs and a face washer to wet down and wipe her over before I put her pjs on. That way I can take her out of the car and put her straight to bed. After swimming I get her home and put her in the shower/was hair and rinse the chlorine off and I sometimes chuck her in the bottom of the shower while I'm showering. I don't bother washing her down though.
I wouldn't stress too much if she missed a bath providing she wasn't covered in food, but it's part of her nightly routine so I'd feel a bit weird about it.
