In an effort to maintain Wendy's naps we still have "quiet time" for Andrew. That means Andrew no longer needed to get into bed and sleep; however, he did need to stay in his room until quiet time was over. Playing with toys, reading books, building with blocks, and running train tracks - all approved activities.
This worked swimmingly for a couple of months. Recently, a new wrinkle appeared in the process. Daddy, is gone for school and work in the afternoon. There is no one awake and in the house to enforce the "staying in room for quiet time" rule. Wendy, due to being deaf in one ear and sleeping on her good ear, does not hear much when she is asleep.
I am sure you can tell where I'm going with this. What does a 3 year old do in the middle of the afternoon while the parent on the house is knocked out?
You climb into bed next to her with a favorite book...and take a nap.
You dump your Cranium board game cards/pieces and a bucket of blocks into the bed next to her...and take a nap.
