Most pediatricians recommend the rice flavor for the cerelec and mine loved it, At first he did not like other flavors as he puked from them buh after a week or two I tried giving him other flavors and he's now accepting them. Babies aren't the same and the how to feed or how much lies all in you because by now I'm sure you know how much is enough for your little one. However you can follow up the instructions on the box, hope this helps..
