Strategic pooping

Noah has been very sneaky lately. Most days, he'll wake up around 5 a.m. I'll nurse him and get him all cozy in his swaddle. Then I gently lay him in his crib and he seems to be almost asleep. I get all cozy in my bed, and as I am about to fall asleep, I'll hear him poop. It's been happening entirely too often lately to be a coincidence. I'm beginning to think that he is doing it on purpose to avoid having to go back to sleep. Little stinker.
