i have been a single parent for many years working FT. I have used a variety of childcare solutions and actually, for some years, it was pretty tough as DS has sensory issues and autism and could not tolerate the fist nursery he was in or after school club. So in the end, I had a nanny who came to the house, which was expensive but the only way to manage.
to the poster who said single parents do the same as any couple - childcare - I don’t think it is the same. If you have no support from the other parent, you need to do the FT job, all the parents meetings, dentists, days off, all domestic stuff yourself. You are the person who is responsible for all the bills, cleaning, buying clothes, gardening, outings, holidays. Nothing is shared. Being a working single parent is not just about finding childcare, it’s doing everything yourself. All the time.
Anyway, to the OP, I would ask around if anyone knows any childminders. I like the idea of a PP to look into registering as a childminder yourself, but that would depend how much demand there is.
a friend of mine does freelance copy-editing but I don’t know how much that pays or how you get into it.
