My DD is 12 weeks old, born at 35 weeks. She is suffering with silent reflux & painful wind & we are struggling a bit. She has been prescribed Infant Gaviscon but can't have it at every feed as it can only be administered 6 times in 24 hrs and she still feeds more than this, probably 8-10 times. After little to no improvement, she was prescribed Aptamil Pepti 1. We phased it in over a few days & she has been on it for 9 days exclusively now. We had 2 fantastic days around day 5&6 where she was settled, smiley, no real problems with wind or reflux... Then end if day 6 and since, it's as bad as it's ever been. GP prescribed omeprazole which we started yesterday & told us to discontinue the Gaviscon. This led to the worst night we have ever had with her - we are lucky that up til now, nights have not been too difficult & she has not been distressed and crying. This has kept us going through the really difficult days. GP said that day 9 of Aptamil Pepti 1 was enough to conclude that it probably wasn't related to CMPA and agreed that it seemed sensible to revert to the Cow&Gate Comfort with Gaviscon X 6 a day and omeprazole. So we've done that from this afternoon but she is immediately distressed after every feed & must be exhausted as isn't getting anywhere near enough restful sleep. I'm just looking for some words of wisdom / experience / advice. How long can it take for omeprazole to take effect? We've seen how our baby can be on a good day & it is really upsetting to see the difference, not to mention the impact on our daily lives, as it makes leaving the house pretty impossible...
