Thanks for the advice, I guess I really just needed assurance that I was 'in the clear' to still have him nap. I have been telling him at nap time that he needs to rest and be quiet as others are sleeping and that he may not scream as I will not come get him before quiet time is done. I have a monitor that I can see/hear him on, so I can tell if he's actually needing me or just upset at having to be in the playpen. Had one more day of a little bit of screaming and the last two have been fine today he slept for about 1.5 hours and now is playing with the stuffy he sleeps with quietly in his playpen
