Okeydokey. I don't know how old your kids are but if they are close to school age, I would still factor in that one day they'll (presumably) be going to a local school so the dropoff won't be so much of an issue.

I have 2 kids and we're in a 4 bedroom house. We wanted a bigger house because DP is a shiftworker and it makes sense for him to sleep separately some of the time. We have a really big open plan kitchen/dining/living area which I've come to loathe because we're always in the same space. If the kids are watching TV, it means I can't listen to the radio. It also means that it's harder to keep tidy/clean as DP and the kids are in there. So, if I was to choose again, I'd like two living areas or a kitchen that's separate but connected to the living area. Yes, we could turn one of the bedrooms into an extra living area but it's not quite the same.
