Reflux is a nasty, nasty thing and I guess it is very common in babies. A lot of people confuse reflux with colic, but they are 2 very different things and lucky us with our little girl we got to experience both. Colic is where they cry for hours straight around the same time each day and they are unconsolable. Every night for about 6 weeks our daughter would cry between 8/9-12 and there was NOTHING we could do to make her stop...except walk on the treadmill with her, which was exhausting (for the husband). Reflux is intestinal and much more common than colic with babies sensitive systems.
Our daughter had reflux that began to be very noticeable around 2 weeks. She started throwing up a lot of her milk and by throwing up I mean projectile vomiting. She would literally puke across the room and sometimes it would be almost everything she just took down. It was intense. She had at least 30 bibs, because there was not a moment where she was not wearing one due to the constant spit up. She took baby zantac and it was helpful definitely, but really it never went away until she started sitting up on her own.
Our son was only spitting up a little bit which all babies do, so we thought we may be in the reflux free zone, but he had a lot of congestion in his chest that you could hear while he was eating and then milk would come out of his nose...so to the doc we went and what do you know- another baby with reflux. His is "silent reflux", which basically means he doesn't throw up, but still has the other symptoms. We suspected he may have reflux when he was arching his back while taking his bottle. This is one of the major signs of reflux in babies. He would also cry and be super gassy when taking his bottle.
Our doctor prescribed him with baby Prilosec, which is a compounded medicine so can only be picked up at certain pharmacies, but I have got to say it is really working well. He isn't having hardly any milk come out of his nose and is arching his back much less. He still has a lot of gas that causes him discomfort, but our doctor has said that this is super common in babies and if you want to spend hundreds switching formula, bottles, etc you can, but you really just have to push through and get to that 6/7 month point where they can sit up on their own- which is what we did with our daughter and walah!! Bye bye reflux and hello major improvement to the gassy's. If you have a baby with reflux, hang in there it does get better, if you don't, lucky you, if you have been through it, kudos to you!!
