We didn't used to go to much, but from about 7 months we did more classes and things. Will he sleep in the car or pushchair? I found that if I stayed at home for every nap, I was never going to get out of the house. So now if we have something to go to (for instance, we take a class at 10:30 on Thursdays), I just leave a little early and take the long route there, so she gets a good 30-45 minute nap in on the way. Or alternatively, if you live in town and don't need to drive, just take a long walk to get there while he sleeps. She used to sleep much longer (1-1.5 hours), but I found that it made no difference if her naps got cut shorter and actually we were both happier to get out of the house and do something. My daughter is nearly 14 months and still showing no sign of dropping her morning nap.
