I have a 2 month old baby. He is strictly bottle fed and he is on Enfamil Gentlease. He seems to be very gassy, fussy, burps a lot throughout the day. He seems to have trouble pooping at times. When he does go, it sounds very explosive. His stools will be very loose and watery. Sometimes you think he is done going, but you go to take off his diaper and he is still pushing out his poop, but like I said it is really loose & watery. Could he be allergic to his formula?
