Transitioning off a bottle is a gradual process that works best with consistency. For 1-year-olds, you can start by modeling drinking from a small, open steel cup during mealtimes. Straw cups are also highly effective for oral development; if your baby struggles, you can teach them the sucking motion by having them practice with a dropper or a small open cup first. Keep the transition low-pressure by offering water in the cup throughout the day, and use a small steel cup that is easy for them to hold.
