Hi my son is 9 months and almost outgoing his graco infant seat by size. I saw these convertible seats at Target and couldn't pick one. Does anyone have any suggestions on these? He really sweats in his infant seat and doesn't like it so I want to avoid this. I know the price is good, but is either one good or is it best to get a newer style? Let me know what you think. Thanks! I hope to go tomorrow if one of these is good.
