Bobby Comfort Fit Carrier

So I finally managed to get myself a wrap... this one says starting at 8lbs which most of them do.

I tried to out baby girl in it (she's 3 weeks old now) and it just seems like she's way too small..

It seems like her little legs aren't big enough to stretch out as far as they need to go? If that makes sense.. maybe I'm just doing this wrong.

Can anyone share their experience with this wrap, perhaps im just failing at life and can't figure this simple contraption out.
