Yes, this is an upgrade to the previous Babybjorn carriers. The BabyBjorn Baby Carrier One is intended to be the only carrier you will need allowing multiple carrying positions and weight options.
Yes, the BabyBjorn Baby Carrier One is for children 8 pounds up to 33 pounds and 21-39 inches. Plus there’s no need to buy or attach an infant insert! With a newborn you just use a zipper for higher-up positioning. This means no additional infant piece that can be lost if you chose to have another child.
The thickness of the BabyBjorn Baby Carrier One made it a bit hot during the peak of the summertime heat, but for the other weeks of the summer and the cooler seasons the carrier would be ideal. It does not have a rain/sun shield so I had to buy a hat for the baby. I can also easily wear a jacket over the carrier to keep myself warm during chilly days.
Yes, this is probably my favorite features of the BabyBjorn Baby Carrier One, it allows multiple users of different sizes to use the same carrier. The straps adjust similar to a backpack. One strap around the waist, one on each shoulder and a back strap connector that can be moved up and down based on personal comfort (this back strap is the hardest of the four to adjust). Once you set the babies size up initially you will not need to adjust the settings until the baby grows.
