12 Month Old won’t use a sippy cup

Cl

I’ve bought 6 different types including soft tips, hard tips, straws, 360 cup, handles, no handles, and a few more variations.. he just bites them and throws them and won’t drink! I’ve showed him how and that water comes out but some have a stream that is too fast, or he can’t get his mouth around it to figure it out and the straw ones take so much effort to suck out.

His ped told me to stop with his baby bottle but I’m not about to have my kid dehydrate, he just won’t use them! Any advice?
