According to Levi you don't need much of it. He fights it tooth and nail some days and others he goes to sleep no problem. We separate the boys for nap. Nathan is miserable without a nap and Levi would just keep him up. Levi needs a nap but not as long of a nap as Nathan. Unfortunately in order to keep Levi in his room to nap we have to double gate him in. I was going to take a pic of the setup but Levi started to wake up. Most days he is fine and plays in his room till he eventually falls asleep. Others he will scream at his door, slam his door, and use every excuse in the book to come out. Today was a screaming day. He usually wears himself out and then goes to bed. Today, for the first time, he didn't make it to bed.
