This particular baby wrap is great for its age. Believe me, it was belong to my youngest sister and she's 20 years old now!
When I was a kid, mothers wraparound their babies was a pretty common thing. Hambin had been used long before it became commercialized ; now that we can find it by using ring, buckle and much fabric choices.
Yes in here baby wrap, we call it hambin. Pronounce it correctly HAM-BIN, not HEM-BIN.
