we decided it was time to get jackson a new car seat. he hasn't quite outgrown the infant one, but we found this one for such a good deal ($80 cheaper than at target), we decided to get it now. also, he's constantly pulling his head up while in his infant seat, so i think he'll like sitting up a bit more. we haven't gotten it put in the car yet, but we let him try it out in the house. he seemed to like it, but who knows, maybe he doesn't really care.
the nice thing about the seat we chose is that it's a 3-in-1. it can be used as an infant seat (it reclines) up to a booster seat. so it'll be the last one we'll have to buy for him.
