Happy Cup + Straw System (5-Pack)

My 3-year-old figured out the straw within a day, and I like that the valve means no leaks when the cup gets tipped over. The lip rounding he's practicing is a nice bonus at this age.

The straw valve actually takes real suction to get water out, which is exactly why my 3-year-old had to figure out lip rounding instead of just biting and letting it dribble. Took her about a week, now she's drinking from a regular straw at restaurants without me packing a cup.

My 2-year-old went from sipping to actually drinking through the straw in about a week, and I credit the lip-rounding design on these cups. The 5-pack means there's always a clean one ready, which has honestly cut down on my dishwashing.
