4mo getting hysterical whilst nursing

[NotSayingImBatman]

DS2 has suddenly begun crying, arching and generally making himself very unhappy whilst BFing.

He has reflux and is being treated with Gaviscon, I can't see any signs of teething and have been to the docs to rule out ear infection. The doctor suggested weaning (bottle and solids) but I'm reluctant as I weaned DS1 early for reflux and all that happened was I had stinky, staining orange puke to deal with.

Any ideas as to what might be upsetting him? He's always been a fantastic feeder until now.

Maybe the gaviscon isn't managing his reflux anymore and need to try something else?
I'm no expert though, hopefully someone more knowledgable will be along soon!

I did think it could be the reflux but the gp seemed reluctant to consider anything other than early weaning.
