Tommee tippee hard spout and handles cup. Tum tum or melii Abacus straw cups. Any 360 rim cups. Straw cups without valves are recommended but for occasional/no spill use the 360 or straw with valves is fine.
We use a tum tum weighted straw cup. Took a few days for my little boy to learn how to use it but it seems to work well and he can be left with it without too much spill!
Tum tum weighted straw cup is the best for us. The water doesn’t spill whilst he shots it about x
