I agree with Kidlove ... at that age he is perfectly capable of following the simple direction of 'it is time to lay quietly and rest' ....everyone has a quiet time at my house and in 5plus years I have never had a child who 'wont/cant' rest quietly ~ they might TRY once or twice to resist quiet time but they quickly learn it is just easier to rest when everyone else does cause here if you do not rest quietly at REST TIME so that you have energy for the afternoon than when everyone else is up and having fun in the afternoon your option is to 'do quiet restful things' in the book nook and I make sure it is a really great natural consequences cause I make sure I plan something EXTRA FUN for those who rested well that day for them to miss out on

Honestly I have a 16 month old who has been sleeping on a cot since 9 months old cause he has some issues with clausterphobia or something in the pack and play and even at that age he was quick to master that it is quiet time and you need to stay on your cot until I invite you off .... IME children are FAR MORE CAPABLE than we typically give them credit for
