T.T.
When my first daughter was born she was not breathing and needed her lungs cleared, she had 22ml of fluid sucked out of them... she never had a problem with breathing after that... My point is there is more than likley something else going on... Get a second opinion!!! An infant that chokes and vomits while sleeping is NOT normal!!! My best advice temporarly would be to have her sleep in a swing, car seat, vibrating bouncy chair to keep her at a semi-sitting position to help her breathing. PLEASE get a second opinion...
