Caleb walks in the room a few minutes ago saying, "happened, mommy?" holding the "4 Month Check-up" sheet that had been taped into his baby book.
I scurried to the living room where I had left the baby book safely tucked into the coffee table cubby hole to find this:

*sigh*
Thankfully, he didn't rip apart the actual pages of the book or remove any photos. I've learned that if Caleb says, "happened?" he has broken something and can't for the life of him figure out why it now won't work.
After that pat on the back, I should have put that book in a very special place where little toddler hands can't reach. Lesson learned.
