Holly is on Nutramigen AA, which is esentially the same thing. They are both made from amino acids, and both taste disgusting! Sometimes LOs won't take to it straight away, as it tastes so different to normal formula. Luckily, Holly didn't even notice and within 4 weeks all her symptoms went. If LO won't take it, some paeds recommend sweetening it with a little brown sugar, or milkshake syrup. You can also use vanilla essence, but make sure it is alcohol free. Obviously it's best not to sweeten it unless you really need to, and if your LO is quite young then chances are they won't notice. There are a couple of others on here that have experience of using Neocate, hopefully they'll see this x x
