Car Seat + Stroller

Hi mom’s! I’m working on my registry and gathering information from women I know in my life, and would love your opinion. A few have recommended the Nuna brand, Doona brand, and STOKKE. I have recently come across the Britax car seat which you newborn can grow with, and personally that sounds like a great long term buy. What do you think? What do you have? Do you have positives/negatives with you experience on your purchase? And help would be greatly appreciated 🥰
