I also have a 6 month old. He just started taking naps because he's more active now he tires himself out. We wake up at 6:30 or so and I play with him put him in his jumper and just try to tire him out. He takes a hour 1/2 nap at nine. Now i'm trying to get him to take a second nap at 2, so he wont be so grumpy inthe eve. It takes a while but I just feed him give him pacifier and lay with him. Ounce he gets the idea that i'm sleeping too, it didnt seem to be so hard. It just takes a while and he fights it but in the end a rested baby is much happier than an overtired one. Good luck...
P.S. my son up until he was 3 months or so would only nap in his swing, (theres hope)
