We're always out doing something during the day and as we live a good 20-30 minutes from anywhere, my daughter always sleeps in the car or in the pushchair. It's actually incredibly rare that we're home for any of her naps (actually, I'm pretty sure I can count the times she's napped in the cot on one hand!). The only time she ever naps in a cot is at nursery. If I tried to plan life around her nap schedule, we'd literally never be able to leave the house. So she sleeps in the car while we drive to swimming or music class or the park to meet friends, or we take a walk around town in the push chair after we spend time at the library so she can sleep while I grab a few things I need for dinner that night. If I need to, I leave a bit earlier to let her sleep longer either while I drive around or parked in the car when we get there. I've never turned down going anywhere because she needs to nap. I think getting out and doing things and seeing our friends is more important than naptime. And whether she naps well during the day tends to have absolutely no bearing on whether she sleeps well at night. Sometimes she sleeps 7-6, sometimes she's up 5 times a night, but how much she napped or how much she ate or anything we did that day doesn't seem to determine it.
