One of the bottle/alternative choices we tried was a slanted open-topped cup[1] designed for early open cup training. He actually drank milk out of it when he wouldn't take a bottle, and now drinks water out of it at meals, but if I don't help hold it he tips it back too far and gets a faceful. The hope is for him to learn right away to use a regular cup, and then only use a sippy cup when we need something he can't spill. Right now I'm just treating it as an early lesson in gravity and fluid dynamics. [1] https://www.doidycups.com/ https://www.doidycups.com/
