My first child was 6 and then a few years later and a short break from work, I had another baby. My baby was 6 months when I returned to work. I wasnt a single mother when I returned, but did wind up as a single mother (again) around 6 months after I returned. So this is my second stint at being a single mother whilst escorting.
It's doable. Obviously. But comes with many more difficulties, especially if you are relying on friends and family for childcare as something can crop up. Just throwing my 2 cents in - from experience, it's probably a bit early to be thinking of nursery for your baby. My youngest is nearly 2 and still not in nursery. A nanny, maybe, but hold off on the nursery.
Feel free to PM me if you have any specific questions, I'd be happy to answer them!
