Looking for advice and/or experience to help us please. We have a 18 week old DS (2nd child). Always been difficult to feed (ff). He starts to take the milk, you can hear him take in air and then will scream. Difficult to get him to take any more feed. Feeds range from 2oz-8oz but overall about 25oz a day. He's pretty miserable in the day and uncomfortable at night so doesn't sleep well. He's dropped from 75th to 50th percentile on the last month. Over the 18 weeks we've tried comfort milk, reflux milk and back to normal aptamil. Infacol, dentinox and gripe water for wind. Tommee tippee, Dr browns and Mam bottles and different size teats. Nothing seems to work. I was convinced he had a tongue tie which makes him take on lots of air. Doctor disagreed and is now treating him as if he has silent reflux so just started gaviscon. As expected has made little difference! Anyone got any ideas? It feels like I still have a newborn
