Yes. For consistency sake, and also for safety reasons, your baby should only nap in a bassinet or crib. Napping in the same location that they sleep at night will also help them to learn that their bed is a place to sleep. When putting them on a nap schedule, you might need to hold them and get them used to the schedule for a bit, but once you've nap trained, you should be putting them down in the crib.
