Sippy cup

Brittany

So my son won’t take a sippy cup. I’ve bought like 6 diff ones and he doesn’t like any of them.

At his 1st year check up yesterday his dr said they he should really be off the bottle and just have the sippy cup. Idk what to do she said just take the bottle away and he will learn to just eventually take it but ugh idk I’m conflicted about it. Please help.
