I consider myself quite informative on reflux babies with both of mine being reflux. Losec is best administered twice a day (my little one is on 20mg tablets, 10mg in morning and 10mg at night, breaking tablets in half) each half of the tablet gives about 12hours of relief. I give my little one his at 6am and 6pm. i also break it down in a little hot water and add breatmilk or formula to it and use an eyedropper to administer. After a reflux episode or even after every feed you can give your baby 1ml of mylanta to assist in the break down or prevention of acid coming back up. Also prop their cot up on a 30degree angle.
I tried intant gaviscon and found it didn't work for my two. I stick with mylanta and it works a treat.
Once your little one is having solids, you can add your losec to it and they don't even taste it.
Hope this information is useful.
