Well, YAY - she is lovin' the new food! That is great - it's always wonderful when the babies enjoy eating. On the bag, there should be a feeding guide to help with amounts. So, you could put down an amount, for example - a half day's worth - and see how quickly she eats that. If she eats it right away - then you may not be able to free feed her (at least not at first); you may have to feed her at meals.
