Grae. Silicon scoop bibs are made from a soft, flexible, light weight food-grade silicon and BPA Free. They take control of those little bits that your little ones drop in their laps. Say goodbye to stained fabric bibs, these are stain resistant and can simply be wiped clean with a damp cloth or placed on the top rack of the dishwasher. Grae. bibs have an adjustable neck and can be worn from when they are 4 months to 4 years old. Take wherever you go, in your nappy bag, handbag or even roll it up and pop it in the lunchbox.
