I'd try a doidy cup or as demented suggested, a straw cup. My DD drank from a bottle, doidy, soft spout beaker, free flow sippy, straw cup in that order. Now she prefers proper glasses (19mo) Obviously I don't indulge this unless I have a firm grip on it too... She was very suspicious of sippys until around a year but took to a doidy when we started weaning at 6mo. They all have their preferences, just buy or borrow a few different types of drinking vessel I should also mention she refused to take milk in anything other than a bottle until 16mo, and then only accepted a sippy because we went cold turkey with them. In her mind, bottles were for milk, everything else for water. Now she'll have her morning milk in a sippy or straw cup (she has it sat on our bed so no way I'm risking an open cup!).
