So as some of you may have noticed, my DD is getting to be quite the big girl. Using our home scale she weighed in last week at 18.5 pounds. DH and I had already been looking at convertible car seats, but it looks like we may need to make a decision quick since our current safety seat is only rated to 20 pounds. The only one I really like so far is the Britax Decathlon. Maybe the Britax Boulevard. Baby's safety is my main concern and I know Britax is the best, but I just wanted to know if anyone had any recommendations or opinions about infant seats. Do any Britax owners have negative feedback? Do those of you who have something else want to add an opinion? Any help would be appreciated. TIA!
