Teething?

I wonder if you're finally teething again as you have been waking up 4-5x at night for the past 3 nights after 'sleeping through' for more than a month. It was blissful to have a good night's rest and am dreading this effect of lack of sleep. It's difficult to complain though as I really want you to have more teeth. You only have the 2 lower teeth which is tad too little for a one year old :) I have caught sight of the upper front tooth cutting through and am hoping this will pass quickly. I want to sleep through the night again!!
