S.H.
Dont' just offer the cup at meal times.
Just leave out several, on a low coffee table, where she plays. Get her acclimated to seeing it and even if she just plays with it.
Don't nag about it. Just leave it out.
That is how I "introduced" the sippy to my kids, from a younger age.
Then they took to it on their own.
Not forcing it.
Or try a straw cup. Some kids like that better.
I didn't give my kids juice either until way after 2 years old. And only watered down 50-50 with water.
All the best,
Susan
