This isn't for the women who've always invested in their appearance and for whom taking care of their looks is as automatic as looking after their health - who've never questioned whether it's OK to spend money on clothes, skincare, etc.
It's for women like me who perhaps grew up with mothers who thought make-up was for vain women who clearly didn't put enough food on the table for their kids. 
Or maybe you grew up with a version of feminism that disdained make-up, but even though you don't necessarily hold to that you still feel a bit guilty about being interested in it.
Or you've just internalised the idea that spending money on yourself - on decent clothes that will last, on skincare that isn't 2.99 from Superdrug, on makeup from department stores rather than the supermarket - is inappropriate now you're a mum.
How do you get over that guilt? If you have, how did you do it - what did you tell yourself? And if you haven't, why not?
(And actually, if you've never felt any guilt about it, why do you think that is?)
