Advice Please

I have been wanting to switch Addison from her bottle to a sippy cup ever since she started feeding herself. I have tried two kinds of cups. First is a hard plastic cup with handles and is not spill proof. The second is a silicone top which is like her bottle. She refuses to stick either of them in her mouth. I have tried putting her formula in both and she just won't take a sippy cup. It is borderline irritating to me. Any advice on how to make the transition or what brands/cups to try?? If you can post links to the product it would be wonderful as well. Thanks for the help! :)
