organicKidz created the first Stainless Steel Baby Bottle and first Thermal Baby Bottle and now we're bringing it to you with even more innovation! Our new Baby Grows Up set is a complete Stainless Steel Bottle Kit that grows with your child! organicKidz Stainless Steel Baby Bottle converts to a Sippy Cup and then to a lunch box ready Water Bottle by simply attaching the accessories included in the kit as your baby grows up. This Baby Bottle keeps liquids hot or cold for 6+ hours making it perfect for the parent on the go, on play dates, traveling, daycare or just about anywhere else? Peace of mind that baby's food is at the right temperature. Unlike glass and plastic bottles, organicKidz Stainless Steel is naturally bacteria resistant, unbreakable and light weight. This kit includes a 9oz Thermal Baby Bottle, 3 vented silicone nipples (slow, mediuma and fast flow) with accordion flex to reduce air intake allowing baby to drink continuously without gasping for air or drinking bubbles, a silicone sippy spout, matching handles, stainless steel lid, and a leak proof bottle cap. The stainless steel lid doubles as a 2oz measuring cup for easy formula preparation or breast milk measuring or a snack cup for little fingers. organicKidz Baby Grows Up kits makes a great gift from newborn to toddler and to preschool and beyond!
