Warning: this post is gross.
I was putting Sam into his bed last night and noticed that there were a couple bunches of raisins clumped together. As I pulled them up closer to my face to look at them (the room was dark), I smelled that they weren't raisins. Thankfully they were clumpy and not sticky. I pulled all the rest of them out from the top of the bed and underneath the sheets. Then I explained to Sam that we only put our poopies in the potty. We don't pull them out of our diaper when we're napping. The sheets are washed, and we've all learned something new.
