Just a couple of ideas. Hope something in here helps....
We use Tommee Tippee too. Started out with just 30mls of cooled boiled water (so that DS could lift the cup). I gave it to him when he was sitting in his highchair -- that worked better than in my lap.
What colour do you have? Not as crazy a question as it may sound. DS has four in different colours and definitely likes the blue one best

.
Also, have you tried different fluids? DS wouldn't take formula or fruit juice at first. Just water. So maybe if you tried a new taste (??)
