I'd hold off giving the greens until after the baby has had at least one good bug feed each day, you may need to resort to handfeeding if she is no longer interested in the bugs on offer.
I had a similar issue with Peppa and Toothless, so I held off giving the greens until about 3 - 4 pm and with their 3rd meal. I actually chose to give Peppa and Toothless crickets for their first two meals , and gave them some silkworms (on a fresh mulberry leaf) with their greens (the silkworms rarely lasted long !).
I was very pleased that they loved their greens as babies, but it's crucial that very young beardies get lots of high quality insect protein and dietary calcium to ensure they grow and thrive and develop properly.
Also , it could be if you are giving BSL maggots , they may be getting too small to be of interest to her or she's bored with them, time to swap over to medium silkworms maybe.
