Hi C.,
My 9 month old has reflux. Not only was he spitting up, but he would occasionally projectile vomit. It's such a terrible thing to watch... so much throw up coming from this tiny body. I recently read that ALL babies have reflux for the first 3 months and that many doctors are medicating babies that don't need it. When our baby started to puke more often, we brought him to the doctor and the nurse practitioner just blew us off. She told us that if he was throwing up after every feeding, or if the projectile vomit could hit the wall across the room, then she would be concerned. The following week our son saw the PA, who took us more seriously. She immediately sent him for an abdominal ultrasound to check for pyloric stenosis (testing positive would require immediate surgery). She also put him on Axid, which he still take 3 times a day (since he was 2 mos old). Amy is right, the doctors are more concerned if the baby isn't gaining weight, which wasn't a problem for us. I am still breastfeeding, but I have heard from other moms that the nutramigen is the best, but very expensive. Find out if your insurance will cover the cost. Some insurance companies will, but they don't want to advertise that.
Here's my advice: No one knows your baby like you do - trust your instincts. As far as excessive spit up, stock up on bibs and burp cloths. Expect to do lots of laundry. After my son threw up on the couch several times, we decided that I would always feed him in the same seat, "the spit up seat," which I kept covered with a sheet. Much easier to throw the sheet in the washing machine then to clean the couch!
It's been 9 months, and I still get stressed out dealing with this reflux. Most babies grow out of it by 6 months. Not our son. Now it's a little harder because he eats solid food and it isn't pretty when that comes back up.
If your son does have reflux, there are several different medications out there. You can google it - you wouldn't believe how many other people are dealing with this. Personally, I'd rather not medicate my baby unless it is really necessary. The axid that he is on doesn't actually stop him from spitting up. It lessens the amount of stomach acid that his body produces, so that when he does spit up, it isn't burning his esophagus.
Some of the signs that we noticed with reflux: he was sometimes fussy during feedings, or even after feedings when he should have been full and satisfied. He would arch his back from the burning feeling of the stomach acid. Obviously, the excessive amounts of spit up and throw up.
Try to keep your son upright for 30 minutes after he eats. This is hard to do if he falls aleep eating. We used to let our baby nap in his bouncy seat because he wasn't laying flat.
I really feel that my son's reflux is one of the reasons that I have had a hard time adjusting to being a mom. I would get so upset when he threw up, even though he usually looked relieved after it. I would call up my mom crying and ask her to come help me (and I DO NOT ask for help!) Things have gotten better, but it was tough for a while. I know how stressful it can be, especially with your first child. If you ever feel overwhelmed, feel free to contact me. I hope some of this helps you - sorry, I tend to ramble once I start talking about this! Best of luck and Congratulations!
PS - If it gets to be too much, ask someone to watch the baby for a bit, and do something for yourself. You will feel better, and it will make you a better mom!
