I just bought a new native pouch off Ebay and I think it may be the wrong size. I am 5'3 145pds and I have a 6mt 16pd baby. The pouch is a size medium. When she is in the pouch she hangs down to the top of my thighs. Is that normal?? Also I have not washed it yet if I do will it shrink?? If so how much?? I really want this to work. I have had a ring sling, and a moby and don't care for either that much. HELP!!!!!!!
