Most spilled-proof sippy cups the on market today come with a valve to prevent spills and leaks. However, most of them are difficult to drink from because it requires a ton of sucking for a small amount of liquid. Is the trade-off worth it for a spilled-proof cup (less mess for parents) when your child is hungry or very thirsty and his/her needs are not met right away? Ihave tried myself to drink from a sippy cup and it was not fun at all because I had to suck and suck which left my jaws soared. Not only my jaws got soared but the muscles in my neck hurt from constant sucking. Drinking from a regular cup without a lid is not that way and this can be confusing when using a sippy cup vs a regular cup.
Poli sippy cup features an adjustable valve where parents can adjust the right flow for their child. Every child’s preference is a little different when it comes to flow rate. Our patented valve is built in on the inside of the spout. Some kids prefer a slow flow and others might prefer a faster flow. The easy and faster flow is easier to drink from because it requires very little suction. The faster flow can be used for thicker fluid such as formula and smoothies. The valve never gets lost and cleans easily in the dishwasher or with a sea sponge.
