DS has always been a good feeder, apart from the early days when he struggled to stay attached with my fast let down. however, the past few days some feeds he's getting extremly fussy - either pulling off, moving his head back and forth heaps, or pulling off within a minute of starting the feed and he starts screaming - i then have to hand express a little and sort of hold it in his mouth for a little bit until he fianlly attaches and feeds properly.
Some feeds I know he pulls off because of the fast let down choking him, as when he pulls off, I have a squirter! But other times, when he pulls off, this doesn't happen.
Any ideas what the matter might be and tips for dealing with it?
