That young, I would give her unlimited pellets, hay, and alfalfa. And I’d slowly add veggies. Sounds good. In my experience, young bunnies looove to eat, and do nicely at eating a variety of foods. Keep going, sounds good. But I would avoid the papaya treats. Being dried, it is easy to overfeed. They still have alot of sugar in them. It’s a good idea not to get a young bunny used to eating sugary foods. My 3 bunnies that I had from an early age don’t get particularly exited over fruit, because I didnt’ feed it to them when they were young. I fed them hay, pellets, grass, and veggies. That’s what they want to eat now, so they have a good healthy diet. My adopted bunny was fed sugary foods, plenty of them, including chocolate. He is a sugar fiend now. He can smell if I have just drank apple juice, before I come into the room. He goes nuts when I walk in after drinking fruit juice. He gets squishy poop if I give him fruit. Many bunnies do fine with small amounts of fruit. Your bunny sounds like he is eating great. I wouldn’t spoil it with the papaya.
