Seeing you’ve already got her on a diet plan and she is showing no ill effects – stick with it! My only ‘suggestion’ would be to offer her more pellets – till they are 6 months old the norm is offer pellets freely. And maybe buy/offer her pellets for ‘young rabbits’ (Alfalfa based) or try an Alfalfa hay. This is best for young bun’s. And don’t ever feel bad that you ‘may’ have done the wrong thing – I didn’t know ANY of this till I met BB!
The veggies sound good (YUM actually!) – I also give my boy whatever we are eating along with what I actually buy for him, like Kale (yuck! – for us), just double check that it isn’t a NO NO, like white potato, etc., and keep in mind some buns don’t love everything – my boy hates zucchini! And only introduce one new veggie at a time and in a small amount, make sure her tummy doesn’t react to it? 1 to 2 cups of veggies a day along with freely available pellets (till 6 months) and hay – when she’s grown up, she’ll never want to leave home (just like my adult son!?!?).

She’s adorable! Compeletely irresistible, as you say =)

Her diet seems fine. You can add some high quality pellets for growing bunnies, f ex Oxbow. The reason you should introduce veggies slowly is that it can be a shock to their little tummies if you don’t. Since this obviously hasn’t happened to your bun, you can keep giving her veggies. Variation is always a good thing. One veggie can be exchanged for another,but not all veggies at once, then back again and so on. You seem very capable and responsible bunny-owners! Cilantro, mint and basil are great treats and a million times better than the yucky crap pet-stores sell, like yogurt-drops and seed-bars that are actually very unhealthy for bunnies.

If she’s not had any pellets in your care, introduce them slowly, just to be safe. Any sudden changes in a bunny’s diet, especially when adding stuff that has a higher nutritional value, can make the stomach flip out.

She’s adorable. I think stick with it if it works too. I would minimize the spinach though to once a week or cut it out entirely – it’s high in oxalic acid (maybe the highest) – it’s okay on occasion. I think it would be safe to start introducing more greens too for a wider variety.

Yes definitely get some high quality pellets and introduce those to her as well. I know it’s suggested unlimited but I think I would still measure them out and see how much she actually eats per day – you still want her to eat her timothy hay and not fill up entirely on the pellets.

Since your rabbit is still fairly young you can increase her pellet ration by a little. Just don’t go overboard lol, some rabbits will overeat. Avoid buying pellet mixes that have a lot of random add ins like nuts, colorful pellets, and corn. They’re unnecessary and overpriced. I used to feed alfalfa based pellets when mine was young since he was eating timothy hay. Later transitioned to timothy based pellets when he got older.

Seems like you’re doing okay.  If you want some suggestions on treats and stuff, the Binky Bunny website has a store that has some good stuff (I don’t order it, but my local pet store carries a lot of the Oxbow products, which seems to be a favorite brand on this forum.  I mostly look at the BB store for ideas).

And don’t feel too bad, my bunny was a complete impulse buy too.  Looks like neither of us could resist soft fur and a cute face lol
