Hello T.,
I would think you could gradually introduce sippy cups for a few meals and snacks each day. Just as I weaned my duaghter off a bottle they need time to learn and get used to how to drink out of a sippy cup. You need to decide what beverage you will transition to as well. I personally went from formula to soy milk and water because my family does not drink milk. Sippy cups are great because they allow toddlers to teach themselves without so much supervision on holding to prevent spills. My daughter is now 3 and is now able to use a regular cup most of the time without spilling but the sippy cups allow for great practice.
