That’s fine.
She just needed to get comfortable I think. She's devouring whatever I put in front of her now.If she’s been eating romaine for a year it may take her a while to get a taste for other foods. Plus romain doesn’t take a lot of effort, leg wise. She will have had some dandelion relatives in her native home so they should seem familiar; hopefully it doesn’t take her too long to adjust to it. You could always try her on a red flower, if you have a safe one. A bit more attractive to her than yellow.
She sure looks small in that picture. Room to grow.
