Ergonomically designed nursing bottle for ease of use even with the smallest hands. This improved nipple is using a patent pending insert and a 2mm hole at the tip rather than the common cross cut. This prevents leaking while still letting milk to flow freely during the sucking motion of the calf. A newly designed air vent allows enough air in as the calf is drinking, regardless of the drinking speed. This air vent also prevents vacuum build up and bottle collapsing. Due to the hole design, the nipples will last much longer compared to the conventional cross slit design. Nipples are available in Snap-on and Screw-on versions.
