Sorry just read your appointment post, thats is great you've had some improvement!!! Still, reading your most recent post, your bubs still sounds a bit like our bubs who would (once he got the hang of breastfeeding) overfeed a lot because of reflux.. to soothe the burning feeling in his throat. He had silent reflux most of the time.., later it became more just chucking up after every feed, and is onyl settling now in the past couple of weeks. I found the best things that helped were baby wearing (keeping him upright to sleep on me), and keeping him upright after feeds, reclining his cot with a wedge so he was not completely flat, and the cranial osteopath..
Sorry I have not read through all the posts so not sure if you have already explored this and asked for a GP opinion on reflux.. as KMN said, you probably wouldnt need meds unless they are really distressed by it, we never ended up using meds.. there are other natural alternatives out there too if it comes to that..
