Sippy Cups?

Heather • 💍 3/17/16 💙 12/19/16 💗 5/23/18
I've been trying to introduce a sippy cup to our little guy (several times now), and he has a blast chewing on the rubber end of it, but has no idea he can get something out by sucking on it, hasn't tried that at all. Any suggestions on how I can help him figure it out?
