@bubblebee40 - very similar to you. Our nursery fees went up 3 times in one year.
A friend of ours says when they stopped paying nursery fees, it was like winning the lottery. They have 2 children, had a flat in east london then moved to zone 6 in South West/East london. I could not tell you where our money went before nursery fees.
Also you are looking at prep schools. Could you consider waiting until year 2 or 3 to move the little one to a private school? Also, do you have a prep school in mind. We had a look a few years ago and found that the term fees seemed to be what we were paying PER MONTH at the nursery.
Also, I agree with others that the 15 or 30 free hours help (I can't quite tell which one you qualify for...) But most London nurseries still make you pay a hefty top up fee. It's more like a "discount" than a strictly "free" service.
We did have a number 2. For whatever reason, it ends up being that when the first one starts reception, we start paying nursery fees for number 2. Also, I staggered my return. I return before the one year mark, part time so I get a bit of a salary whilst being able to do some pick ups/ drop offs. Then full time at the one year mark. This,I hope, will help a bit with finances. Also, look around at nursery fees. We changed nurseries for that reason.
@40hello "Keep all her clothes and shoes and pass them down. They can share a room." Yes to this. If you end up having a different gender, it's surprising how much can still be re-purposed. Otherwise, try and find someone local to do clothes swap.
@StayAlert "We had a second child in London but waited till DC1 started reception before having DC2 just so we were not paying 2 lots of nursery fees at the same time" we did this too not by choice. Hopefully it works out.
