thanks for the replies. We are using the formula in conjunction with increasing the foods in his diet that are high in iron to try and increase he's intake. We beleive the reason he is anemic is that he has been ill and not eating and has lost weight over the past couple of months, but has recently started to get his appetite back and we are trying to increase his weight at the same time. If we are unable to improve both he's weight and iron intake in a certain period of time, we may have to look at alternatives, and it could indicate something else being the cause of the anemia - so we are keen to give the change in diet the best shot first.

I think he is starting to get used to the taste of the formula, He had it today without complaint - might of helped that it was really chilled (had ice crystals).
