I’m looking for recommendations for an all in one car seat that’s good for both of my girls (6 months and 3 years). I currently have a safety first seat for my oldest that converts from rear facing all the way to a high back seat (100 pounds). I want to get them matching seats. I want good quality for a reasonable price at about $200 max per seat.
