Some babies just don't like having their legs froggied. Mine didn't either. Having their legs extended in a wide, legs out position may seem awkward, but is much better for them because it mimics a natural sitting posture, so their weight is being supported by the bum and legs rather than the pelvis. If she is uncomfortable, she'll let you know! The main problem is if their legs are too short, you can tell because the edge of the carrier will rub up against the backs of the knees. The only SSCs (well, buckle-tais really) that allow you to narrow the width of the seat for smaller babies are Connectas and Pikkolos - these can be used legs out from newborn. But anything with a heavily structured waist cannot be cinched - and most are more suitable from 3-4 months onwards, and really come into their own as toddler carriers.
