Nesting Instinct

Archer is in full nesting mode lately. Every day for nap, I have to build him a "nest" to sleep in. Some days he even pretends to be the baby bird who sleeps in the nest. I never know where he'll end up; sometimes the nest, complete with 10 blankets and 25 stuffed animals, migrates during nap time. I wonder how he can sleep in such odd positions...behind the rocking chair, under the train table, in the laundry basket. Strange kid.
