How long will it take for my son to get use to the hypoallergenic formula?

My son is now 4 weeks old. Since the day he was born(4 weeks early) he has done nothing but throw up. We started on regular similac, then to sensitive, next soy. Now he is on nutramigen. I feel he has gotten worse with the throwing up. He was projectile vomiting before we switched him and now he isn't but he is still throwing up most of what he has eaten. It has only been about 12 hrs since we switched but I was hoping to see some changes. Does anyone know how long it will take if this does work? The dr said if he isn't better in a week they will do a sonogram to see if he has pyloric stenosis. They don't think that's it but don't want to rule it out.

  • As far as I know, you can usually see a difference immediately. Take him to a different Dr. as soon as possible for a second opinion please.

  • I have changed his dr twice (Im really picky). He has seen 3 different drs in a month. And in two weeks he has only gained 3 ounces. Current dr said they were worried but not extremely concerned because he has gained some weight. I was thinking of taking him to some specialist. But I have no idea what kind or if that would even help.

  • Find a doctor and stick with them. Doc shopping doesn't do anyone any good and you end up with no one actually following him.

    I'd give it a full 24 hours before you give up. You may be switching too frequently and this is causing him further digestive issues.

  • 24 hours.

    Let me throw this out for you... it's possible to get him on the breast. If you don't want to, that's fine. But know that it's a possibility.

  • Every doctor I find doesn't seem to care enough. He was projectile vomiting in the hospital after he was born. They let me take him home the next day. And my milk never came in. He was premature and it hadn't came in yet and it still hasn't. But I never tried to pump or anything because I didn't like breast feeding with my first child, Because I have thought about that. I cant afford to buy the breast milk that people sell. Im not switching him from formula to formula. Its the drs. They all knew how long he was on each formula...

    I am not being rude by this comment by the way. Just stating whats going on. Sorry if it came off in a different way.

  • Stay with ONE doctor so ONE doctor has all his records and they can narrow down what's wrong.

  • No worries. I'd head to the nearest Children's Hospital, let him spit up all over them and camp out there till they figure it out. It does sound like pyloric stenosis.

  • My son did this. His second doctor. Switch him to three diffrent formulas. Then he sent him to Cooks foe a sonagram on his tummy. We found out that he was born with an air bubble almst the size of his tummy. NO wounder he could not keep anything down at all/ At that point in his life.

  • All the drs are in the same clinic. He goes back to the dr today. He got worse on the new formula and has an allergic reaction to it. I am hoping they do a sonogram to see if they can figure out what is wrong. Its getting worse and its extremely frustrating.

  • Go to Facebook and check out Eats on Feets. It's donated breastmilk. At most you'd pay for shipping, which will be cheaper than the formulas you've been paying for.

    Also look for Human Milk 4 Human Babies. Again, a donor site.
