I wrote a similar thread about a year ago. Got great advice, the best was to literally carry her like a baby almost already folded/sitting position(if that makes sense? lol) and just plop her in the seat and quick put the straps on. When I was carrying her to the car on my hip and then moving her out in front of me, it allowed her start to wriggle before even getting in the seat.

ETA: It was a phase, but I still use that method now
