My boys have been on Similac Alimentum for over a month and I noticed that the formula is definitely a lot thicker then the regular formula. With the Alimentum formula I am able to use the Dr. Brown level 2 flow nipple.

Wow, those are great weights. At the 4 month visit my boys only weighed -- Trevor 13 lbs 8 oz, Peyton 11 lbs 14.5 oz, and Maxwell 12 lbs 15 oz. I think my heaviest one will only be close to your lightest one in weight at the 5 month visit. I'll ask the doctor about the Enfamil Gentle Ease and Enfamil AR.

With the boys reflux there is hardly ever any spit-up. So I believe they have silent refluxes, b/c I do see them scrunch up their faces and make a slight gagging face during feeding.

Just recently we switched Peyton over to Prevacid, he takes 1.6 ml 2x a day. Maxwell is still on Pepcid, but his dose has increased from taking .35 ml 1x a day to .35 ml 2x a day. In addition, I've beeng giving them 10 ml prune juice. The feedings has been somewhat still difficult but not as bad as before. I spoke to the pediatrician and she recommended that I should take Peyton to see a Ped Gastro...so I have an appt scheduled towards the end of Sept (that's the earliest appt they have). If everything checks out ok, then the pediatrician will refer me to a feeding group.

I'm really hoping by around 6 months this reflux issue will go away.
