I hardly used a sippy cup. The only way she ever would use one was with the valve taken out. She got milk from a bottle until she was 3, and learned to use a regular cup (with no lid) by about 14 months at the table with meals. Sippy cups are not a requirement, they didn't exist when I was a kid. If spilling is an issue, the plastic cups with the little spouts in the lids can work.
