I used these for my two children! I used three size M swaddles only at night. My children were able to sleep soundly when wearing these, so they were a great help (⁠◡⁠ ⁠ω⁠ ⁠◡⁠) Perhaps because my second child was very active, the hand areas are slightly stretched, but there are no noticeable stains, and the fabric is still in good condition, so they can still be used. I am also selling other Swaddle Ups. If you purchase multiple items, I will discount each item by 50 yen.
