Help with sippy cup!

meagan • ♡𝓶𝓸𝓶𝓶𝔂 𝓸𝓯 𝓽𝔀𝓸 ♡

My little man won't take a sippy cup. I've tried 3 different ones and he just isn't getting the hang of it. I offer it everytime he's eating solids and even sometimes when he's sitting on the floor.

Any tips? Should I try a new one? I added pics of the ones I have tried. So far I've been offering the Nuby sippy cup. (Last one)
