It sounds like she basically hasn't lost weight (2g out of 104g is basically within the margin of error). If it were me, I would probably offer something live that was young enough (eyes not really open, just crawling around) to be safe to leave in overnight and go ahead and leave it in overnight. I wouldn't try for f/t right now, because if she does have a tongue issue, it would be better to have the best visual and heat cues you can, which would be live.
