A question about going back to work with young children, and school holidays

Hi everyone, I have a bit of a stupid question that I’m worried will make me sound like an arsehole. I’ve been a SAHM since my eldest was born (he’s 9 in a few months) and I’ll be going back to work next year. My question is, what do working parents do during school holidays?! My partner and I can probably squeeze a week off each for Easter and Christmas, and 2 weeks each for summer but that still leaves a lot! My daughter will only be 3, and will be going to a council run nursery which also closes for the holidays (Scotland)

We have nobody else who can look after them and my daughter will be too young for the holiday clubs that my son could go to. How do you all manage?
