Hi, my son is 5 months old and up until recently he was having 6oz every 3 hrs, 3 weeks ago he got a cold and that knocked his feeding all over the place, after that he had his injections which also disrupted his feeding then after that he got another cold and is currently left with a hacking cough he cant seem to shift. I am lucky if I get 4oz down him in one go at the mo, he was on 30oz a day now its more like 25oz. He was born at 6lb 6oz and went down to the bottom centile line, after a few months we got him up to the 2nd centile line. I know it doesn't matter where on the chart they are as long as the follow that line. We are so worried hes gonna drop off the chart now. Is 25oz a day enough
