Hi, Im sorry to hear it's been so bad but I know exactly what you are going through- I've been through it 3 times!!
Yes, all 3 of mine had it for the first year of their lives. They were only on Omeprazole as Gaviscon doesn't work with breast fed babies and I didn't want the extra stress od giving meds with every feed. I was given Domperidone too but though it was also useless.
If she takes the dummy use it. My two DS's did but my DD refused and it was worse. What I did was, before they were 6 months (and much happier anyway) was throw them away so there was no issue later.
I also slept DD and DS2 on their tummies. I had a sensor pad attached to the monitor so the light flashed with every breath and an alarm would have sounded if they hadn't taken a breath after 20 seconds - which of course never happened!
Babies with reflux sleep so much sounder on their tummies as they are not suffering the pain they get when lying on their backs.
Have you propped her bed up with a good amount of books?
Never over feed a baby with reflux and keep her upright for a good 20/30 mins after every feed.
You probably know all of this but just incase.
Apart from that im surprised you have had no relief from all of that medication. The Omeprazole is the best and most expensive drug. What I did was split the dose. Make sure she is on plenty. I upped mine slightly and slowly until they settled then split it.
oi id give say 10 ml in the morning then 10 mls in the evening instead of 20mls (pink tablet dissolved in water)in the morning as I found it would wear off half way through the day. Obviously I checked all of this with the GP first.
The more she grows the more meds she will need.
I just feel your meds aren't working properly. Are you checking in with the GP's or Pediatricians?
You should be getting more relief by now than how you describe.
I wasn't afraid to tweek the meds myself by DC3 but you will feel more comfortable speaking to the Doctors id imagine. Some GP's are a bit clueless and waiting to see the Pediatricians can take that long the baby has grown out of it! I found the GP wanted me to give 5mls and the Pediatricians would say 20mg straight away.
Renitidine is faffy isn't it? Not convinced about that one.
The only other thing to remember is she will get over it. You will too even though it feels like hell. If she screams so much you are going to die, switch the hairdrier on. The white noise will stop her in her tracks and give you 5 mins to regain yourself. Just don't fall asleep with it on. I had to get it downloaded onto my I pod for this reason!
When the meds are bang on she will improve. When she gets solids she will improve more. When she sits up she will be fab and when she is running about it will all be forgotten - trust me. My 3rd baby is 16 months and it's only reading your post that has jarred my memory and reminded me why I can't have anymore!
