So, I just learned that my MyRide 65 expires at the end of the year. Yeah!!!! So, I need a new seat for my husbands truck. It's the ones where the back doors open the opposite way. FF for an almost 5 year old. She's on the small side. Last time she was weighed a month ago she was 32 lbs. And maybe a rec for a booster seat for an almost 7 year old? We have the evenflo Big kid amp in there, but it doesn't really fit him well. We have a britax parkway sgl in my van which is awesome, but I was wondering if there way a cheaper option.
