My DD is in a Recaro Pro Sport. She just turned 4. At her last doc appt (about a month ago) she weighed 39.2lbs and was 41.5 inches. I noticed in the fall that when we are putting her in the seat, she has to contort her arms to get them under/into the harness. I took out the additional (bottom) seat padding to see if that helps, but it doesn't and my DD noticed the difference in cushioning. I don't see any other adjustments I can make to the seat to correct this issue. She is far from reaching the height/weight limits of the seat. What's up? Is this something that happens with all car seats as the kids get bigger? Anyone else experience this?
