My son is about to be 4 months on Friday and weighs 16 pounds. His infant seat is good up to 30 pounds.
My question is can we leave him in his infant seat until he hits 30 pounds and do we have to switch to one of those bucket seat looking car seats or can we go to the convertible car seat? He is sitting up almost completely unassisted already. I just want to start shopping now so that I can get a good car seat that is in our budget (I am currently a SAHM so we don't have a lot of extra money around the house). Thank you.
