Quick answer
Most babies are ready to try a sippy bottle around 6 months, when they can sit with support and show interest in drinking from a cup. The key is to introduce it gradually, starting with one sippy session per day while keeping familiar bottle feedings for comfort.
Why a sippy bottle, not a cup, first
A sippy bottle uses a soft silicone spout that replaces the nipple on your baby’s existing bottle. This means your child gets a familiar grip and flow, but learns a new drinking skill—tilting and sipping instead of sucking. It’s a gentler step than jumping straight to an open cup or straw cup.
The trade-off is that some babies may resist the new spout at first. If your baby refuses, wait a week and try again. The transition can take several weeks, so patience matters more than speed.
Signs your baby is ready for a sippy bottle
Look for these baby drinking milestones before introducing a sippy bottle: sitting with minimal support, showing curiosity when you drink from a cup, and being able to bring objects to their mouth. Most babies hit these around 6 months, but some take until 7 or 8 months.
If your baby is still fully reliant on bottle feeding for nutrition and comfort, it’s fine to wait. There is no rush—starting too early can lead to frustration for both of you.
Your decision rules for the bottle-to-sippy transition
- Start at 6 months, but watch the cues: Offer the sippy bottle once a day when your baby is calm and not overly hungry. If they push it away, try again in a week. No single age fits every baby.
- Use the sippy for one meal, bottle for the rest: Replace one daytime bottle feeding with the sippy bottle. Keep the morning and bedtime bottles unchanged so your baby still gets comfort and full nutrition. Once your baby accepts the sippy for that meal, replace another feeding after a few days.
- Expect mess and practice: Your baby will dribble, gag, or spit out liquid at first. That is normal. Stick with water or expressed milk to avoid waste. The soft spout is gentler on gums than hard spouts. If your baby chews the spout instead of sipping, gently guide the bottle upward so liquid reaches the spout opening.
