Hi have just come across this post too as I'm starting uni in September and need to sort childcare for my 3 youngest after school as I won't get back until after 6pm which is after school club closes.
Last year I did an Access to Higher Education diploma at our local college and there were people there doing maths and English GCSEs at the same time. The college actively encouraged parents to study, they had a nursery attached to the college that was 8am to 6pm hours.
I think there's some funding available for younger students but not sure. The college may have a hardship fund which as a single parent, I qualified for my travel costs to be reimbursed. As a mature student I got nothing else funded, so have scraped by this year on tax credits and child benefit and a discretionary housing benefit payment. Just about made it but we've had no holiday this year.
Looking forward to my student maintenance loan come October.
Good luck and don't give up x
