What has happened to my super happy, sleep through the night baby? He as been replaced with a fussy, drooly baby! That's right Will is definitely teething. I didn't know this would happen so soon. I had gotten used to him sleeping from 8:30-5:30. I miss my sleep! Also, he's nursing so much during the day, I can't get anything done. Is this going to happen with every tooth? How long will it last? I hope it's over soon. Until then, Sophie the Giraffe has become his best friend.
