When and how to introduce a sippy cup

When transitioning your baby from a bottle or breastfeeding to drinking out of a cup, sippy cups can be a great tool. Babies can start using them as early as 6 months, and sippy cups can make it easier to phase out bottles eventually. Try offering your baby a few ounces of water, breast milk, or formula in a sippy cup after starting solids, at around 6 months old. Only give your baby a sippy cup during specific meal or snack times, since sipping on anything other than water throughout the day can lead to tooth decay.
A sippy cup is a training cup with a screw-on or snap-on lid and a spout or straw that lets your child drink without spilling. You can get models with or without handles, as well as different types of spouts.

Sippy cups can be a great way to help your baby transition from nursing or bottle-feeding to a regular cup. They can also improve hand-to-mouth coordination. When your baby has the motor skills to handle a cup but isn't quite old enough to keep the drink from spilling, a sippy cup can give them some independence while keeping cleanup to a minimum.
