We'd like to buy the baby bibs, the details is as the below: It is something the mother or father places over the shoulder to absorb what the baby will spit up when the burping process begins. It serves 2 purposes: 1) catches what the baby spits up so it does not land on cloth or furniture 2) fabric is clean so baby's face is not sitting on potentially dirty clothes. These measure approx 7.5" x 20", 36g per pair. They are 90% cotton and 10% poly.
