My nearly 9 week old has gone from 75th at birth to 40th percentile. He's EBF but it's not been easy but getting better. He has relux and will only feed when sleepy but does feed every 3 hours most of the time but doesn't feed for long before he pulls off the breast then goes back on and off every few seconds, it's a frustrating way to feed. He does feed better during the night. How can I get him to feed more often and for longer? He doesn't seem hungry before 3 hours so maybe I need get him to feed for longer but once he's done he won't go back on and gets distressed. I feel so guilty that's not gaining much. He's alert and smiley but also gets quite unsettled and cries mostly in the evenings.
