I have a Boba Carrier 2G in the adorable "Tweet" pattern. It is brand new, in the box! It has literally never been used. We ended up with 2 of them but only need one so this one has just been sitting in the box. This is a soft structured baby carrier, similar to a buckle tei or Ergo, but I think it is way better! It has full leg support which makes it much more comfortable for toddlers. It has incorporated foot straps that hold the child's legs at a comfortable angle. It can be worn on the front or back and can be used up to 45 lbs! My son is 35 lbs and I have a hard time carrying him unless he is in his Boba. It's the only way that doesn't kill my back! It was also great for when he was smaller because I could nurse him in it comfortably. It has a sleeping hood that stays rolled up until you need it. I would just pull it over his head and he could nurse away or nap in privacy! My husband loves using this more than any other carrier we have tried. They are super easy to use unlike a lot of other baby carriers that are out there.
