Personally I do......
kinda because at this point most days he gets at least one nap in the car and a couple times a week he is in the sling for awhile at the store - may or may not nap. And I still keep him with me at church, so he usually sleeps in the sling there. And at home we have been bouncing back and forth between naps in the crib and with me on our bed, though I often get up when he falls asleep.
I love the idea of him knowing that when he gets in the crib he just goes to sleep, but our lives are such at this point I cannot be home everyday all day so he has to adapt. And I think it is good for them to realize they can sleep other places besides the crib - stroller, carseat, sling, etc and give you a little more flexiblilty without losing your naptimes altogether.
Anyway - that's my 2 cents worth!
