Hi there, I was only able to bf DD til 8 weeks so I'm sure there are people here to help with much more insight than I, but I couldn't read and not post to offer support.

The coughing and spluttering does sound like reflux - DD had silent reflux and it was very uncomfortable for her, and once she moved to ff and the silent reflux was diagnosed, we managed it with AR formula. I also have friends who had fully bf babies who had reflux which ended up being managed with medication, so don't feel pressured into giving up bf!!!

Is he still having wet and pooey nappies? If not, and you are concerned about his hydration, perhaps a call to the ABA, or Health Direct, could offer more support.

Good luck love.
