We made it to 3 years old rear facing. Will continue to do so until she maxes limits on her next fit.

Shes TALL! 34 lbs and 39 inches long. Her next fit goes to 40 lbs and 49 inches rear facing so we have plenty of time to keep her this way.

( only bad thing is that she learned to stretch down and loosen the straps by pushing the button , so she can get her hands in the inside of the harness😩😔)
