Protect your baby's sensitive gums with our super soft spout sippy cup. It's been perfectly designed to help baby progress from breast or bottle to their 1st Tumbler. Each cup comes complete with our patented 2 in 1 non-spill valve that gently regulates baby's drinking action so the flow of liquid is always smooth and steady - and without messy leaks and spills. That's not it though - every valve can be removed easily to convert your sippy cup to free flow - THE CHOICE IS YOURS! Our Baby's 1st Tumbler is made from safe BPA free materials.
