I have been using a mei-tai which I absolutely love. Our toddler has gotten big enough to make front carries awkward. In a back carry I found it difficult to keep the straps from cutting into my shoulders, and from rubbing the backs of his knees. We also do a lot of hiking and found that the mei-tai made it difficult get him up and down frequently. A friend had a Lenny Lamb Ombuhimo and let me try it. I fell in love and bought this one. I love the adjustability, flexibility, and comfort. Our toddler loves the feeling of freedom. We are very happy! Bonus- the shipping was super fast!
