Make absent parents responsible for 50% of the costs of childcare rather than leaving the entire burden on the resident parent.
This could be done by allowing absent parents to claim Tax Credit help with those costs.
Childcare does not just enable the RESIDENT parent to go to work, it also enables the absent parent to go to work, so why are all the costs borne by resident parents?
It could even be done through maintenance and the CSA.
My Ex-P fully understands that when I go back to work, I will expect him to be liable for 50% of the childcare costs. If he can rearrange his working hours do that less paid for childcare is needed, then the costs will be lower, and so will his portion of those costs.
When we were a couple, childcare costs wouldn't have come out of 'his' wages or 'my' wages, they would have come out of 'household income'. So why should I have to bear that cost alone if we are no longer together?
If it means that he has the DC's on every one of his days off to lower the childcare costs, then it is no different to how it would be for me.
Equal parenting means an equal share in the COSTS of parenting, of which childcare is one.
Also, charging £52 a day when someone on NMW only earns £45 a day, well, something doesn't quite add up there, does it?
I think, in essence, what the Government is asking here on MN is "How can we reduce the bill for the childcare element of Tax Credits."
Cynical? Moi? 
And there are only three ways to do that, all being needed to be done simultaneously :
-
Make absent parents responsible for 50% of childcare costs, as the likelihood is that their career wasn't interrupted when the DC was born, and they don't have to arrange their working hours around Nursery & After-school club pick ups, so because of both these reasons, they are likely to earn more, and NOT be claiming Tax Credits, thus reducing the Tax Credits bill for childcare.
-
Put in place a lot more state funded Nurseries and after school care, following the Swedish model, that is AFFORDABLE even to those on the lowest wages.
And 3) Make employers pay their staff a LIVING wage rather than the current NMW, which would enable them to cover their childcare without recourse to Tax Credit childcare element.
Unless and until all three of these things are done, childcare costs will continue to cripple mid to low income couples, and be unattainable for Lone Parents in NMW jobs.
HTH.
