So, I really really want to get DS well and DD Radian XTSL ....DS is 3 yrs old 37.5 inches and 29 lbs...DD is 15 months about 18 lbs and 29 inches...they would both get a lot of use out of them BUT they are sooo expensive...AND I have a serious car seat buying problem (as i know many of you do) in the last year I bought 2 MyRides which ended up weirdly being incompatable with my car...a True Fit Recline which was supposed to be for DD but DS had so much growing room in it I gave it to him and turned him back RF....so to be cost effective I bought the Onside air and i hate it! I mean she looks comfy in it and all but its hard to tighten/loosen the straps...its hard to use with latch...I have also bought a Frontier 85 before I turned DS back around RF....soooo as you can see DH would probably not be so happy if I bought one more car seat haha! but i really want them LOL! Anyway sorry just a little vent!
