DS 7 weeks is FF and has mild silent reflux. He has been much better on a combo of comfort formula + gaviscon. I make feeds with 70deg water, rapid chill then store in fridge. Reheat and then add gaviscon and shake. Using number 2 teats on tommee tippee bottles. The teats are getting blocked. Any suggestions? Faster flow teat, something else? DS1 never had reflux. I used to add powder to room temperature water and feed. I know it's not what you are meant to do. I want to do the same with DS2 but I tried it and the blockages are even worse! What does everyone else do?
