here to read about it. Well, I finally figured out why he was doing that. It was because of his tooth! Every baby handles teething differently, and apparently when mine is about to cut a tooth, his bottles go out the window. The day his tooth cut he started taking his bottles again no problem. We went about two weeks with him not taking his bottle, and about two weeks of him taking them before he started refusing them again. When this started back up, I looked in his mouth and noticed the second tooth coming in. The only thing I can figure about why he does this, is that his bottom jaw must be really sore from the new teeth that it makes it really uncomfortable for him to suck. I'm already on the highest level nipple, and if I cut the holes to make them bigger the milk will just pour out, so I can't do that. The only thing I can do is give him smaller, more frequent bottles when he's cutting his teeth, and keep the Orajel and Infant Tylenol on hand. I've found that the smaller bottles work really well when he's sore, because he gets enough to satisfy him for a couple hours, plus he's not sucking for as long of a time which makes him less sore. The Orajel offers him instant relief, and I give him the Tylenol when all else fails. After the Tylenol, he's much more comfortable within 20 minutes. Another thing that's been helping him through the teething process has been more naps. He's been taking a lot more lately, and has been falling asleep within a couple minutes of laying down. Still not a whole lot of luck in the sippy cup department. I bought a couple different types of cups and he's still kind of confused. Surprisingly he's done the best with the Nuby cup. After his tooth cut he figured out how to get the liquid out of the mouthpiece. I've been putting a little bit of apple juice mixed with equal parts water and letting him practice with that.
