BREASTFEEDING FEATURES Unlike metal d-rings, our non-slip neck clasp won't loosen around your neck while nursing. The extra large burping cloth helps mothers burp their baby during and after breast feeding. The burp cloth fabric adds weight to the bottom of the nursing cover to prevent it from blowing up in the wind. The rigid neckline helps mothers maintain eye contact with their baby while breast feeding. 100% cotton fabric is breathable and safe on your baby's skin.
