So most nights, either Spike or myself read a book to Brock before bedtime. Well we noticed that if he starts getting fussy before we start reading, he'll calm down as soon as we open a book and start reading! Then, the last two times we read to him he actually fell asleep (like a deep sleep, out for the night kind of sleep) as soon as we finished the book! How cute! He loves story time! He doesn't look at the book yet, but he stops fussing and wiggling around, so I assume he's listening! :-)
We also noticed that Brock started rubbing his eyes when he's tired and ready for bed! I guess I assumed this was a learned behavior, but neither one of us do it! It is the cutest thing ever!!
