When are you suppose to introduce a bottle. I am a little worried due to his reaction to pacifiers which he does not like at all! He has this look on his face like it taste bad and usually gags if he actually gets it in his mouth. He actually puked the one time when we offered it. I have tried different tyes of nipples and no matter the size, shape, texture he does the same thing I am worried he will do the same with the bottle!
