Sippy Cup

My son has been using a sippy cup for about 2 months now.

He has figured out how to get the water/milk out of them and play with it on the table.

I doubt there is a sippy cup that won't leak. But we have a soft sprout, a hard sprout, straw, and a 360. He will just hit it on any surface.

And I dont like to take it away, I want him to be able to drink water when ever he wants.

Any sippy cup suggestions or tips?

Oh and a side note y'all pray for me. He has 4 top teeth coming in at once. They are almost thru the gums.
