Mayb me Pandora? I took DD to RCH. She was a huge chucker (90% of the bottle everytime and went through about 50 bibs a day). We took her to the RCH when she was about 5 months old as i was just over it all. Found out the tube in the throat area(i cant for the life of me remember the name of it) wasnt closing off at all, so it was like a 2 way.. it could go down but then straight back up again. Usually there is a flap that closes over in most people that stops the food from coming back up. We went through every formula known to man and none of them made a difference. It finally started to improve about 7 months old (seems like for ever away i know.. ) but remember, its only bad coz you are living in that right now. She was put on Losec for reflux.. but she threw it up aswell.

Its not good for them to change formula so much so quickly. Try and give it 1-2 weeks minimum on the same formula to change it agaain. I ended up settling on S26 GOLD, which she was on until 2 weeks ago (17 months).
