Hi sez, is your LO still suffering from his reflux? My little boy puked constantly even with the Gav so I weaned him off it at about 13 months and he was no worse or better. He is now 19 months and still has the occasional puke but seems to have grown out of it. The doc said when he was walking it would improve as he is upright most of the time and gravity keeps the food down and he was right.
Cant help with the other milk, sorry. Is he waking because he is hungry or habit and wants a cuddle and is he taking 3 meals plus snacks during the day? You must be shattered getting up through the night all this time.
Hope this helps.
