Hi, spoke to my sister and she changed him over to aptimil. He started on it at 4 weeks, and gradually increased it till he was on it completely by 6 weeks. When he went back on the gaviscon it was just half the recommend dose as the doc didn't change the prescription from the first time when he was just little. Then as of tues last week they upped it (though still not the max as he takes varying amounts of his feed) and a couple of days later he started doing formed poos, and once it was little hard pellets. After speaking to the health visitor on the thurs, they reduced the amount again. The extra gaviscon did coincide with a reduction in his crying, but it was also around the time he had his vaccinations so may also be to do with that!
