My LB is 4 weeks old and EBF. In recent days he seems to have developed silent reflux - lots of gulping air, squealing, writhing and kicking when feeding, and then struggling to settle after. I've read up and it seems the main advice is to keep him upright for 40 mins after feeding. But this doesn't seem very practical as I feed him to sleep (even before the reflux we were struggling to get him to settle in his crib). Any other tips / advice on how to deal with this?
