B turned 4 in December and is almost over the top slots of her XTSL. I have a Frontier she can use until about April when I start watching her new baby sister. Her mom and dad are ready to move her to a booster full time in their cars but I have talked them out of it this far. Am I crazy to start booster training in my car so she is ready in her parents cars? I'm so not ready for her to be old enough to be in a booster! she is 4 years old, weighs 57 lbs, and I'm not sure on exact height but she is even with top slots on the XTSL.
Either tell me this is a good idea or an awful one!
