I would keep at it, sometimes they are just uneasy about new things. Oreo devours anything sweet before it can leave my hand lol…I don’t give them many treats, so she gets VERY excited for carrots, blueberries, strawberries and probably any sweet fruit, but I’ve kept it to the ones I just mentioned. But Blu on the other hand is VERY hesitant to try anything that isn’t a green lettuce. He even has picked around chicory (until I kept at it enough that he tried). I thought for sure he would NEVER eat fruit because he used to do what Bee was doing…and mostly looking scared like “what are you trying to poison me or something?” Finally after several attempts, and it was a lot of times I tried, he loves blueberries … At first he wouldn’t even touch a carrot!! And he loves those too… I haven’t had success with strawberries with him yet. But I would suggest cutting them up into pieces as well..that’s how I first got Blu to try the blueberry.
Lastly, your buns are SO ADORABLE! That little Bee is too cute!!
