M.,
I'm so sorry you and the boys are going through this. My second daughter had reflux from birth to 9 months. She is 10 months now and I am STILL catching up on laundry. She also got very constipated on the rice cereal so we switched to oatmeal. Prune juice can cause stomach cramps so I wouldn't use it anymore. Try oatmeal without the prune juice. It helped a little, but unfortunately nothing worked or seemed to alleviate my daughter's discomfort. Medication did not work either. We ended up going to a specialist who explained that there are two kinds of reflux in babies. Physiological (which is what my daughter had) where the baby is uncomfortable and throws up, however is otherwise happy and meeting their milestones, etc. Medication does not help with physiological reflux and it's more of a laundry problem and discomfort with no longterm health issues or acid damage. Babies with physiological reflux usually outgrow it by 9 months (although some can have it until 18months). The other is Pathological reflux where the baby is constantly in pain and is never happy, never smiles or laughs, and is not meeting their milestones. Medication does help in this case, however the bad news is that it is not always outgrown and can be a problem for many years and some require surgery.
My daughter slept through the night starting at 8 weeks. Then around 4 months she started waking at night and sometimes needing a bottle. They go through growth spurts so the trick is to feed them more during the day (add an extra feeding somewhere) or talk to their doctor about starting them on food - it really helped with us because solids were easier for her to keep down than liquid. I think it also felt good on her throat because the food was more soothing and cold. We started with oatmeal then baby food. Just be sure it's nothing that would contribute to acid. To this day, we still put the oatmeal in her bottle because that's what she's used to.
Also, I do believe the reflux contributed to the restless nights. She did start sleeping through the night again and goes to sleep all on her own for naps and nighttime. It's wonderful. It's just a phase they go through. It's good that the pacifier helps them go back to sleep. I don't believe in letting them cry for more than 5 minutes. If they're not going back to sleep, then it is because they need something or are uncomfortable. Your instinct will tell you. Hang in there. I know what it's like being sleep deprived. My first daughter didn't sleep through the night until she was 2 years old!
My guess is that your boys also have physiological reflux so it's just a matter of time. They will get better. They grow so fast. Sorry this reply got so long. I'm just trying to share everything I learned because it was such an upsetting experience for us --- especially not understanding it. So I'm hoping to provide you some insight and hope. Please let me know if you want to talk more. One tip- stock up on aprons and wear them so you won't have to change your clothes as much. I was changing her and me several upon several times a day. I'm assuming the boys throw up all day like my daughter did.
I just wanted to follow up with another piece of advice and another piece of info. We would also many times put my daughter to sleep in her infant carrier (car seat) in her bedroom (or even in the crib). That way she was really propped up and more comfortable and she slept so much better. At the same time she was in her room/crib so it was familiar. Once she was able to roll over, she ALWAYS (and to this day) sleeps on her stomach. An adult friend of ours with reflux said it's VERY uncomfortable flat on your back. So until you are ok with them sleeping on their stomachs, I would use the car seats for sleeping. More info: When I asked the GI specialist about allergies, she did not think that was the case. For one, it didn't matter what type of formula we tried (soy, enfamil, gentlease, nutramigin, etc.) The specialist explained that the muscles that usually close the valve between the stomach and throat were underdeveloped and that is why the food is coming back up. She said the reason babies outgrow it at around 9 months is because that's when the muscles usually mature. Again, this is in the case of physiological reflux. I'll send positive thoughts your way. It will get better. K.
