Both of my daughters had the exact same problem...I assume when you say throwing up, she is not projectile vomiting, just spitting up after a feeding. That is what my girls did, and with my youngest (who is now 11 months), it was sometimes up to 7 or 8 times after one feeding. We kept checking her at the doctor to make sure she was still gaining weight, and we did at one time put her on the Zantac, but it only seemed to help a little. The main thing that helped for us was giving her the Enfamil AR lipil. The good thing about it is it doesn't really reduce the frequency of the spitting up, but it makes it a little more solid, so not as much comes up each time. Before, it would seem like a whole bottle of milk would come up, just because it was so liquidy and would go everywhere.
But to get to your question about teething, that is exactly what I decided really made it the worst for my youngest. Whenever she would stop teething for a little bit, she would stop spitting up as much, and whenever she would start spitting up again a lot, I knew a tooth was about to come out.
So to give you some hope, it will get better. My little one VERY RARELY spits up anymore, if at all. And again, it seems to only be when she has another tooth coming in.
Good luck, and have fun washing all those clothes...I have to say I'm very glad to be beyond that finally. :) And you will be, too, soon enough.
