my baby is mostly great. he sleepsnall night and is mostly happy. but when he eats its like his stomachs on fire and he screams when he's got to burp. when he's done with his bottle about 2 hours later, sometimes he "spits up" this clear liquid. it looks just like water. he goes to the doctor tomorrow so i will talk to them then but do you all have ideas on what it could be? he is 2 months old and drinks Enfamil Gentlease formula.
