Welcome and congrats!!! If she is still under a pound I wouldn't go messing with her food just yet
With one so small you worry about blood sugar and the stress of going to a new home is enough to deal with right now. I would give her time to adjust and really watch her eating patterns and gradually adjust to set times, and yes multiple feedings when you get to that stage is a good idea. Did you get any info from your breeder about low blood sugars?
Again welcome to YT and Congratulations on your new baby!! We love pics and would love to see both of your babies
