H, any advice gratefully received. First grandson is 9 weeks old and was born at 36 weeks at 4lbs. He has gained weight well and is now 8lb 2. When he was 6 weeks, he couldnt keep a bottle down and was prescribed omeprazole which seems to work although he still seemed windy. 3 weeks later, although good weight gain, he seems to be almost back to how he was. He is generally happy but does seem uncomfortable especially during late feeds and night feeds. Thoughts? Thank you
