This is actually an important developmental stage. In newborns the gag reflex is far forward in the mouth. As babies put things farther and farther back in their mouths it moves the gag reflex to the back of the mouth (where it is for us). If the gag reflex continues to be toward the front, it can create big eating issues, so don't worry!
Also, as one mom said, try not to react at all. Even if she vomits, just clean it up without comment and move on. Gagging can become a purposeful behavior if it gets attention.
Finally, be prepared for more gagging as she tries new food textures and flavors. Don't give up if she gags on the first bite...by the 3rd or 4th the gag is usually gone. It takes at least 20 different "exposures" for a child to truly like or dislike a food. If eating becomes an issue, don't wait...call your Early Intervention program for help!
