Carseat

What carseat would you guys recommend? We have this one since he was born and he just looks too big for it already. I don't know how but he does.

He is over 18 lbs, probably about 28 inches long. He is only 4 months but was born a chunky baby. 😀

Planning on buying a new one but would want something that can transition with him--more like a forever carseat, I guess.. It's just that they have a million in the market for me to choose 😩

Let me know if you recommend a specific brand or type. 😀😀😀
