Hi, MKIRD. What a great milestone for your little one! I would think that as long as she uses the litter box regularly to poop and pee that you won’t have to help her any more, but keep close track for a while.
If she were still with her mother, she’d still be nursing. It makes sense to me that she is still looking to you for her nourishment. Think of this as quality time you are spending with her. 🙂
