I figured it out!!

Oliver has a new tooth on the top left. I'm fairly certain now that it is the reason he wasn't sleeping well. He slept for 7 hours last night. OOOOOh it was great!

When Oliver does something impressive (like crawl across the whole room or pull up) I have been saying "I did it!" and clapping. Well yesterday he pulled up on my leg and so I said "I did it!!" then he looked right at me and said "Ididit!" It was sooooooooooo cute!
