I used these only at night for the first month after my baby was born. There were no spit-ups, so there are no noticeable stains. I bought these because my baby would often startle and wake up. Since these are used every day, I thought I'd need several, so I'm selling three together. I hope they help your baby feel safe and secure ^_^ Colors: Gray x 2, Bear pattern x 1 Size: S (3-6kg) Instant purchase OK!
