Please no. While it is expected that an ADULT BP could go on a fast for one of a few reasons, for several months, a baby of this size shouldn't be fasting at all.
To OP: I too would recommend live. How is your setup? 2 hides, appropriately not in an area/amount of activity which could stress the little girl out? Some of them need most of the sides covered (my girl) and some do not seem to.
