I've used this a few times since receiving it. Unfortunately, the waist size doesn't fit me well, and I haven't been able to use it properly, so I'm putting it up for sale. I still have the box and bag, but please refrain from purchasing if you are sensitive to items that have been stored at home. I think it's very helpful for assisting with breastfeeding and for quickly carrying a child who is just starting to walk. 【Age Range for Use】 From when the baby can sit up (around 7 months old) to around 36 months old (15kg) *This is just a guideline, so please read the included instructions carefully and use it according to your child's needs. *Shoulder straps (sold separately) are not included. Please support your child's back firmly with your arms as it is not protected. *The Velcro on the waist may shift if the child frequently sits down and gets up. This also depends on your body shape and clothing, so it may be better to wear jeans or other clothing that provides more support. Please consider this. 【Color】 Melange Gray It's a dark gray color. It's highly recommended because it's less susceptible to stains and sun damage.
