By never having any money to be honest
I earn a reasonable amount and am the higher earner in the house but make no mistake it's hard going ...currently between two DC (one is at school but needs after school care) I pay around 1100 a month .
Weirdly since my marriage breakdown it's become easier because my stbxh pays very fair maintenance and dp helps with daily living costs but at one point about a year ago I was paying two full time nursery places and it was brutal...i think most months I paid 2500
It's hard because I am extremely fortunate which I am very very well aware of that I physically cam access money to pay that but it can be tough doing long hours at a demanding job then feel like you have little to show for it (and take some crap from others on occasions about using childcare in the first place)
However when my marriage ended because I had been lucky enough to retain my career at a certain level I was able to manouvere my DC through it at a reasonable level because I could pay so the childcare is hard but it kept me able to earn if that makes sense
I will throw a happy dance when ds2 goes to school in two years (whilst quietly sobbing that they are growing up) but I honestly don't think the cost is that unfair...it sucks to high heaven and God knows it puts some women in impossible situations but I do think given the job they do childcare providers do not charge unreasonably at all
The only thing that irks me is when others assume I have family help...i don't that has never been an option outside stbxh,myself and dp. No parents , grandparents or siblings etc to help out but I've come across a lot of people who cannot comprehend that concept and can oddly be breathtakingly rude about that
