Hi! I would say that it depends on what you have on hand. If you just have a bunch of the fuzzies, then just feed her those until she is big enough to take double fuzzies (so you aren't wasting anything). Now, if you have a bag of pinkies and a bag of fuzzies, and she'll take one of each, then go for it. Most of my snakes around 35-40g are just taking a single fuzzy (although I will admit that I'm not sure how much they weigh, they very well could be larger than yours).
