Hi and Welcome to YT!! So very glad you joined us. I first want to say that all of your babies are beautiful. I can clearly see why you are so in love with little Lilly, she is just too precious for words!! And clearly, you are a wonderful and dedicated mommy to her. I don't have experience with this, but want to suggest you post this in the breeder section, alot of experienced breeders in there that will surely have some more ideas for you. I know a few have had some tiny babies, and had to hand feed. Again, welcome to our community and I wish the best with your little tiny baby girl.
