I fit in with DS - easy to say, he has no day sleeps now!
If he had more than a 3-hour nap I'd wake him up though. And no sleeping past 3pm because then he's not ready for bedtime. But that was it. He can fall asleep in his pushchair and stay there or in the car and be carried into his bed... what ever is easiest for us.
DS is really flexible for his day naps. He rarely wants to have them in his cot, but does sometimes. Or he falls asleep on me occasionally - in the carrier it was a lot more often.
Although, DS's naps were co-incided with my day in the first place (as a younger baby). 9.30, in the pushchair for my coffee mornings; DS fell asleep. 11.30, walking home, DS fell asleep. Afternoon I'd have to take him out for a nap around 3-4pm too. So it's easy to say I fall in with DS when he has always fallen in with me too.
I also scheduled appointments and meetings for DS (health visitors and doctors) around his naps. It wasn't that hard when he had fairly predictable ones.
