I'm in Scotland also. Here's how we did it: Saved for a couple of years and also took in a lodger and saved the rent money. We saved up £10k, though we didn't end up needing anywhere near all of it.
Put off buying a family home and stayed in our starter flat with a very low mortgage until I was back to work again.
DH absorbed some of the shortfall when my pay went down and we also used the savings.
We tag team some of the childcare so DD only goes to nursery 3 days. The downside is we don't often get a day when we're both off work, so family days have to be planned. You'll also get tax free childcare from the government, for us that works out at around £120 discount.
We settled for a really small house for our first family home. It means having to be creative with space and storage solutions and is often a PITA to be honest, but it does mean we can afford the nursery fees, days out, things like baby swimming and holidays. Those things are important to us. We will only move up to a bigger house once we're done with the high nursery fees.
I've gone back to work full time.
Don't worry. I too had a panic about how we were going to afford it all but we've managed so far. We're on very ordinary, probably low by MN standards salaries, £25k each (although that is hopefully changing soon).
