I love my Beco Gemini carrier, but the fit seems weird lately. So far I only do front facing in, C is 6 months old, 16 pounds. I cross the straps in the back, have the hip belt just above my hips, no issues there.

C has been pulling her arms up above the straps, like in this picture (not me and C). And then she leans way back in the carrier, seeming sort of unsafe and uncomfortable, though I don't feel like she will fall out or anything. I have the top part folded down, like in the picture, because she hates when it's up and blocks her view, but when it's down her shoulders are pretty high above the top.

Any idea what's wrong? Straps tighter? Is she not sitting deeply in the seat enough? I can try and take a picture later, but I wanted to type this while she naps and I can think straight!
