First Sippee Transition Cups are specially designed for your baby’s first sips. They provide a smooth transition from breastfeeding or bottle feeding to cup drinking, as well as helping to develop tipping and sipping skills
Knock-proof. Bump-proof. Ooops-proof. The No Knock Cup is hard to knock over but easy to pick up. It grips instantly to smooth, flat, solid surfaces, stopping little hands from tipping it over
