I don’t think I’ve ever written public reviews before, but I will now. My son is 4 months old. We've tried 4 different carriers so far, and he hated every one of them. This one was my last hope. I ordered it, and it arrived within a few days. Since it arrived, we’ve been dancing together with my son in it. It's a game changer! Very easy to put on and take off alone, very comfortable for both of us. I carried him for approximately three hours in it yesterday, and neither of us complained. Thank y...
