6 week old DS2 periodically gags/chokes/coughs during a feed. It seems like the milk goes down the wrong way and he has to cough it up again.
It doesn't happen at every feed, but maybe every other one.
I'm pretty sure I don't have oversupply or a very forceful letdown. I virtually never spray milk if a child comes off the breast during a feed. I don't leak at all and haven't even needed breastpads, which I definitely did with DS1. I'm feeding 2.11 y.o. DS1 as well and didn't even get engorged in the early days.
The coughing isn't after the initial letdown, but usually happens further through the feed. DS2 will also sometimes wail and writhe around whilst still latched on (though this is less frequent).
He did have a tongue tie which was revised a couple of weeks ago. It's made no difference to the coughing. I think he may have an upper lip tie though and his top lip doesn't seem to flange out properly, especially at the sides.
He doesn't seem to have reflux, is generally calm and happy (apart from when wailing and wriggling at the breast). He doesn't routinely 'posset', although every 3 days or so he'll throw up properly, with no sign of distress. He gets upset by needing to burp but manages to burp himself quite easily if he needs to.
Any ideas why he's doing this?
