We designed our LittleBoo bibs with newborns and little ones up to 6 months in mind. They have a smaller neck and tie at the side, have 3 layers, the inner one is super absorbent fleece and the outer ones are organic cotton.
BurpyBoo burp towels are made from the same fabric as we use in our robes, they are super soft organic cotton. Towelling on the inside (or outside depending what you prefer) and jersey cotton on the other side and a waterproof layer in the middle so no milk dribbles or spew will soak through to your shoulder.
We added a curve to one side so it fits neatly into your neck and two pockets at either end.
