I'm currently raising my third child, and when I gave birth to my eldest son, I purchased the Japanese authorized agent's genuine product. I used it the most when my eldest son was a newborn, and only a few times for my second son and daughter. There were no instances of spit-up, and the fabric is still in good condition. I think it's close to being a beautiful item. The very stretchy string fits the mother's body without putting any strain on the baby! I loved it. I remember that when I put my newborn in the Boba Wrap, they would sleep soundly for hours. It's designed to be used for slightly older children as well. There are no instructions, so please download them and use them. There are also many instructional videos on how to use it on YouTube, etc. It might be difficult to carry the baby all the time when the outside temperature is hot, but I hope that babies in the coming seasons will be held a lot and have a happy time with their parents! I hope someone will use it.
