WeeSprout 3-in-1 Stainless Steel Cups for Kids are the perfect step up for little ones learning to sip like big kids — without giving parents a reason to stress over spills. These ultra-durable cups are designed to grow with your child, functioning as smoothie cups, food containers, and on-the-go snack jars.
Designed with speech pathologist recommendations in mind, each cup includes a curved straw with an open valve to support healthy oral development and proper jaw alignment — ideal for kids transitioning from a sippy cup to an open cup.
Soft, food-grade silicone straws are gentle on gums and teeth and ideal for thicker drinks like smoothies. Built-in straw stoppers keep straws in place — no more flying messes or sticky hands.
Each set includes both drinking lids and storage lids for maximum versatility. Protective silicone sleeves provide grip, help prevent drops, and insulate cold drinks to keep little hands comfortable.
