I'm in the market for a versatile car seat suitable for infants and toddlers. I currently have two kids and am looking to upgrade so I can accommodate another infant seat in my vehicle soon. I need something that allows for a smooth transition from an infant carrier to a toddler seat, ensuring all three of my kids will fit comfortably. If you have options that meet these criteria, I'd love to hear more about your recommendations and pricing.
