Been having problems with my 10 wo's feeding for a couple of weeks now. He's bottle fed and we're using the MAM bottles. It started with him falling asleep whilst feeding but has moved onto his taking 1-2oz, him squirming away and then refusing more. We've upp'ed to size 2 teets, changed to HIP organic milk and have even tried making fresh bottles so the milk is warm again with no luck. He's putting on weight slowly (born on 91st centile but has now dropped to 51st centile). He's supposed to take 25-30oz a day but I'm lucky if he takes 17/20.. Has anyone else experienced this?
