My daughter is currently 40.75 inches tall and 38 pounds. She is 3 years 8 months old. She is forward facing in two Britax Marathons (not the new 70lbs ones). I plan to keep her harnessed as long as possible so we will be moving her to Frontier 85s. My question is when would you move her? She still has a little bit of growth room height wise before her shoulders are above the top slot on her Marathons but I am concerned with the weight, especially after the Canadian crash test results from a while back. So would you move her....
1) Soon. Do not use the Marathon over 40lbs.
2) Wait until she outgrows the Marathon. (This will be height before weight I am positive.)
