---------------------------------------------------------------------- ● There is no need to upgrade the size of Tutu's nipples ● Super cross cut allows you to control the amount of milk your baby drinks according to the strength of their sucking ● CLOSE state: Normally it is tightly closed so even if you knock it over, milk will not spill, making it safe and clean. ● OPEN state: The amount of milk that comes out is controlled according to the strength of the sucking. ● Therefore, your baby can drink just like they would from mom's breast. Can be used with all of Tutu's "slim type baby bottles".
