Hi I just want some advice regarding changing my 8 week old's formula. He is currently on aptamil 1 but suffers really badly with wind. He seems sore after feeds and takes ages to settle again, just thrashes around especially at night. I've read that some mums had the same problem and changed to cow and gate. Is this worth a try? And how do I go about changing it, do I do a straight swap or gradually? He does have reflux so is already on infant gavsicon, is fed and held upright after feeds and his crib is raised at the head end. I also use infacol which helps bring up wind but he still seems really sore after feeds.
