Transitioning your baby from a bottle to a cup is a milestone that marks their growth into a toddler. It can feel like a big step, but with a bit of patience, most babies take to it naturally.
When to Start Many parents begin introducing a straw cup or an open cup around 5–6 months of age. There is no need to wait for a specific "perfect" time—early exposure helps them develop the oral motor skills needed to suck from a straw or tilt an open cup. You can start with small amounts of breast milk or water, even if they only take a few sips at first.

Open Cups vs. Straws Both options have benefits. Open cups are excellent for developing coordination, though spills are inevitable! To manage the mess, try keeping the open cup for water during meals and using a lidded straw cup for milk if you need a cleaner solution. Some parents choose to avoid daily straw use for milk to prevent "association" habits, but using a straw is generally considered excellent for oral-motor development.
Making the Shift If your baby is attached to a bottle, don't worry. Many parents find success by making the transition a positive event around their first birthday. You can "say goodbye" to the bottle, celebrate the big change, and offer a new "big kid" cup. If your toddler is very attached to a nighttime bottle, try focusing on oral hygiene—ensure you brush their teeth after their final milk feed to keep their smile healthy.

Above all, remember that learning to use a cup is a skill, not a test. Expect some splashing, some spills, and plenty of practice. Model the behavior by drinking from your own cups or glasses—toddlers love to mimic their parents!
