Hello, does anyone know what causes projectile vomiting. my son has done it on and off for a year now. he was born at 34 weeks. he was in the nicu for 5 weeks. he is all healthy other than the spitups. he has times when he is fine and then he will start doing it every day, sometimes up to 3 or 4 times a day. can anyone help come up with a reasonable answer.
