7 week old, ebf. Weight gain fine. Last week or so developed horrendous trapped wind. Takes so long to properly burp him during and after feeds. Can hear the trapped wind. Gripe water brings up man burps. What am I doing wrong? It must be the latch, but I don't know what has changed. Dread the night feeds- have to wake my husband to help wind the baby which I hate to do on weekdays. Any thoughts?
