A couple of suggestions. For the sharp little claws you can use nail clippers and just nip the ends about once a week. That will dull them a bit and also get her used to handling her paws for future nail work. To help for her still needing nursing and mom cuddles give her a stuffed animal. It may sound strange but it can work. I found a small kitten that was too young to be away from its mom. It needed something to cuddle so I gave it a stuffed bunny. It cuddled it and suckled on it. Of course that bunny had to be around for the rest of the kitty's life. It looked old and ratty but when I tried to get rid of it kitty would go in the trash and retrieve it. Thats the only time kitty would get into the trash. I just resigned myself to having this ratty bunny around.
