This is an adjustable nylon baby sling. - Color: Black - Straps: Adjustable - Buckle: Plastic buckle It folds up small, so it's convenient to have on hand. While it's not suitable for long periods, it makes a big difference compared to not using one. It depends on the child's weight. The non-slip (gray) part should be positioned where the child's bottom goes, and the buckle part should be at the back of the person carrying the child. The thick black part goes over the shoulder. The child should be positioned around the waist of the person carrying them. (Photo 1... it might be difficult to see... I'm not sure if this is the correct way to use it) I used it like this. It may or may not suit everyone, so please consider this before purchasing. There are wrinkles from when I rolled up and secured the unused part of the belt. ⭐︎ You might get a good deal if you read my profile! Thank you for looking.
