I prioritise. 24 hours in the day. X amount of energy. Y amount of $$. Z amount of care factor.
Besides I'm too frigging busy to invest any time worrying about what other mothers look like
Eta I actually don't think my image has changed all that much since before I was a mum. I'm probably a bit more daggy now than back then, because I have a baby belly, greys, more wrinkles and less time to shop/put an outfit together/iron. And I'm now allergic to most makeup so can't be bothered with it but meh. Appearance is not my top priority. I'd much rather have happy kids than a manicure.
