Those with a lot of kids, how does the bedrooms situation work out?

My fiancé has two kids from previous marriage, and we have one of our own. We want at least two more!! I’ve always wanted three of my own biological.

Anyway, we are house hunting, and I’m having a hard time with this. I feel like all kids deserve their own room, their own special place that they can go to. despite what others think, this is really important to me, but the lord knows I can’t afford some 7 bedroom house or something crazy!

Just wondering how y’all do it. How many bedrooms do you have, and do the kids share, or how does it work?
