Instructional video clips
Sometimes when choosing a carrier it can be helpful to see them in action- Here are some video clips to help you choose. Or if you already have one these can help if you have trouble. Please keep in mind that with most of these carriers there is some learning curve. Kind of like riding a bike the first few times can be awkward then it gets easy and fun:)
