I have all my kids sleeping in separate rooms in pack and plays and one (the oldest) sleeps in the playroom on a nap mat .... I put them in say good night and shut the door. I never go back in till nap time is over and I have fans running to drown out any noise. Every here sleeps for the entire time except my newest one (14 months) and he no longer cries when he wakes up but just babbles to himself.
