I have a 17 month old son weighing 22lbs. We r using the Graco safe seat for him with weight limits upto 30lbs. His feet have started popping out of the car seat...but he still fits in it. We've adjusted the straps to the top slot..but it has started to get a bit tight near his crotch and shoulders. Do u know how i can adjust it to be able to use it upto 30lbs?
Thanks alot!
