Hi A.-
Both of my kids had reflux and allergies as babies. My son was allergic to milk protein and recently is able to tolerate milk (he's 2 1/2). When he was a baby, we tried several different formulas until we finally got a referral to a Pediatric Gastroenterologist who put him on a formula called Neocate, which is for babies with multiple food allergies or gastro problems. It's expensive, but our insurance covers it, thankfully. Doctors (even your GP or pediatrician) know what to look for to try to figure out what's going on. Each kid is different. My daughter would arch her back and twist when she ate, which the doc said was reflux. My son would eat just fine but wake up 1/2-1 hour later with a blood curdling scream and be inconsolable for an hour or so.
I disagree with some of the advice you have received so far. If it is reflux, most doctors will tell you to try to feed your baby small amounts more frequently, since an over-full tummy is more likely to reflux.
Also, there are things you can do, like keep him upright for at least 1/2 hour after each feeding. Try elevating one end of his crib by putting a brick under each wheel. This never worked for us- both of my kids were/are crazy sleepers! My 5 year old was upside down in her bed last night when I checked on them.
Please know that changing your son's formula is not something to do quickly. You should take several days to transition him to a new formula and stay on that formula for at least 2 weeks, although some drs would say a month or more to determine if your baby is benefiting from the formula change. It truly can take that long to get it out of their systems. If you want to talk more about this, send me a message; I won't bore you with the details. Also, different formulas generate different poops! Just be prepared!
And, finally, don't be afraid of medications. They can make a world of difference in the quality of life for babies with reflux, not to mention diminishing scar tissue being developed in their little throats that could potentially lead to problems in the future. The side effects of these medications are minimal compared to the benefits, in my opinion. Some meds simply coat the throat, others stop acid production- your doctor will know beest. Also, some pediatricians just try a month of a medication without referring to a Gastro. Just be sure that if your son is prescribed a med, to administer it exactly as directed. Some of them need to be given a few minutes before feeding, some with food, some without.
I hope I didn't overwhelm you- I'm just very vocal about trying to help others when their babies are hurting.
Blessings to your family,
J.
PS-The Mylicon drops didn't do ANYTHING for either of my kids. I never tried gripe water because I'm not a big fan of homeopathic remedies.
