Which Will Come First--Crawling or Teeth?

We are taking bets, and the odds are high for both. It seems that pretty soon little boy will be more mobile than we were hoping he would be at 5 months! Lil' D has been sooooo busy changing the past few weeks that I am having a hard time keeping up! At the beginning of June, we transitioned him out of his swaddle blanket, out of the bassinet, and out of our room---all on different nights of the same week. Needless to say, that was a challenge. Then, on Father's Day, he learned how to roll from his back to his tummy. All week last week he would wake up screaming because he was on his tummy and was not happy about it! Apparently, he temporarily forgot how to roll back over!
Finally on Thursday I found him sleeping on his tummy! That was the first night he slept 8 hours straight since about 2 months old. I am enjoying getting a little bit more consecutive sleep time! We are still working on some kind of regular nap schedule, but hopefully getting Lil' D in his room in his crib will help with that!
When Lil' D rolls over onto his tummy, he generally stays there and kicks like a fish out of water. He turns himself around in full circles. He reaches for and grabs toys around him, and he is looking at what we store on the bottom shelves of the coffee table. He also is working on the downward dog yoga pose. Hence the tittle of this post. Lil' D has been teething for several months. He seems clearly read to crawl...whether we are ready or not. Soooooo....we are taking bets on whether he will finally pop that tooth first or start crawling. I am voting for teeth first!
