I'm a nanny and have looked after many newborns, plenty with reflux, with which the 5 wk old I now care for has been diagnosed. We are trying him with all the usual treatments, - gaviscon, omeprozole, zantac, domperidon... you name it...- and he is responding to non of these, which is quite normal, some babies don't and just have to suffer til they grow out of it, and we can help as much as poss keeping them upright etc.
