Having a reflu, baby is such a challenge. I know, my oldest had reflux, aswell as a neighbor and my niece. What meds is your son on? My daughter was on Reglan and Zantac, my niece and my neighbor both were on Prevacid and amoxicilian. All of us saw reflux specialists. My daughter was much better around 5 months old and I breast fed her. My sister used a soy formula for my niece and my neighbor found the carnation good start worked best for her little girl. The two bottles that we found between the three of us was Dr browns and the playtex nurser, the one with the drop ins. My neighbors little girl had to have surgery for her reflux and my niece had to have her meds up until a year. Just a little note.. when you give solids, sweet potatoes seem to upset the reflux and for constipation give pear juice it is the least acidic. Keep a journal of how your child is doing this will let you know what you need to change. I wish you strength and paitence, I know how challenging a puking screaming child can be. You are doing a great job as a mother, just keep asking questions of your dr., and you will find a solution.
