Eating

Drinking from an open/straw cup

Many babies — 12–18 months

Moving from bottle to an open or straw cup.

What’s happening

Moving from bottle to an open or straw cup supports better oral-muscle development than a sippy cup does, and most toddlers can start practicing well before they're fully off the bottle.

How to support it

  • Start practice with a small amount of water in an open cup at meals, over a towel or the sink — spills are part of learning.
  • A straw cup is often an easier bridge than a wide-open cup for a first-timer.
  • Practice matters more than the exact cup — expect months of spills before it's tidy, and that's normal, not a sign to switch back.

When to ask your pediatrician

Drinking from a cup without a lid (with some spilling expected) is one of the CDC's checkpoints for 18 months. If your toddler is refusing any cup entirely by then, or you have concerns about swallowing, mention it at their next visit.
