My son was about 4 months old when I bought this, and was in the stage where he wanted to be held 24/7. He was about 12 pounds at the time. Every time I put him in the sling he cried like a maniac. It looked incredibly uncomfortable for him, his neck was all scrunched up. On the plus side, it was comfortable for ME...if my baby hadn't hated it maybe it would've worked. Also, I was confused becaues NO WHERE on the product did it say 'New Native' which was the whole reason I had purchased the product online, due to favorable reviews of that specific product. Pretty disappointed. My son likes the Bjorn carrier and the Moby wrap better. The Moby wrap is a pain to put on and gets really hot but it has it's good points, namely your kid doesn't look like he's suffocating.
