印尼揹帶 very good and safe. My helper bought the 揹帶 herself when my son was few months old, she said it's more safe for the bb in case she got so tired during the night and accidentally dose off during feeding. The 揹帶 is very durable, and bb loves sitting in it. I am not sure of the cost but I gave her $100 which was more than enough to cover the cost.
