Most babies are ready to start transitioning from bottles to cups between 6 and 12 months of age, though every child develops at their own pace. The key is introducing a cup gradually while maintaining bottle feeds, then slowly phasing out bottles over several months as your baby becomes more comfortable with cup drinking.
Begin cup training around 6 months by offering water or milk in a sippy cup or open cup during meals, while continuing regular bottle feeds. Gradually increase cup usage and decrease bottle dependency over 3-6 months, following your baby's cues and readiness signs. Stay patient and consistent—this transition typically takes time, and every baby progresses at different speeds. Offering praise and making cup drinking fun helps create positive associations with the new feeding method.
Understanding Readiness Signs
Before starting the transition, look for key developmental milestones that indicate your baby is ready. These include sitting upright without support, showing interest in what you're drinking, grabbing for your cup, and being able to coordinate hand-to-mouth movements. Most babies show these signs between 6-9 months, though some may be earlier or later. Don't rush the process if your baby isn't showing these signs—forcing the transition too early often leads to frustration for both parent and child.
Choosing the Right Cup Type
There are several cup options to consider during this transition. Sippy cups with handles and spill-proof lids are popular for beginners since they're forgiving and reduce mess. Open cups or straw cups offer more natural drinking positions that support proper oral development. Many experts recommend eventually moving toward open cups, though sippy cups can be a helpful intermediate step. Your choice may depend on your baby's coordination level and your comfort with messiness during mealtimes.
Starting the Transition Process
Begin by introducing a cup with water during one meal per day—typically lunch is a good choice. Offer small amounts and let your baby explore the cup at their own pace. They may chew on it, play with it, or spill most of the contents initially. This is completely normal and part of the learning process. During this phase, continue offering all regular bottles as usual; you're simply adding a new option, not replacing bottles yet.
Gradually Increasing Cup Usage
Over the next few weeks, offer the cup at multiple meals throughout the day. As your baby becomes more comfortable, you can introduce breast milk or formula in the cup rather than just water. Begin replacing one bottle per day with a cup feeding—many parents start with the midday bottle since it's often the least emotionally charged feeding. This gradual approach prevents your baby from feeling deprived while allowing time to adjust to the new feeding method.
Managing the Bottle Phase-Out
Rather than eliminating all bottles at once, remove them one at a time over several weeks. Most families keep the morning and bedtime bottles longest, as these are often the most comforting for babies. Some children naturally lose interest in bottles as they become more skilled with cups, while others need more encouragement. Watch for signs of readiness and don't push too hard—some resistance is normal, but extreme distress may indicate your baby needs more time.
Handling Common Challenges
Spilling is inevitable and messy, but using bibs and high chair trays designed for spills helps contain the mess. If your baby refuses the cup initially, take a break and try again in a few weeks—forced feeding often creates negative associations. Some babies prefer certain cup types over others, so experimenting with different styles can help.

← Back to All ReviewsMost pediatricians recommend starting the transition between 6-9 months when your baby can sit upright and show interest in drinking from a cup. However, every baby develops at their own pace, so wait until your child shows signs of readiness like grabbing objects and bringing them to their mouth.
Sippy cups with handles and spill-proof lids are ideal for beginners, though open cups or straw cups work well too depending on your baby's coordination. Many experts recommend introducing an open cup around 12 months while continuing sippy cups for convenience and travel.
Most babies take 2-6 months to fully transition, though some adjust faster or slower depending on temperament and readiness. You can start by offering a cup at one meal daily and gradually replace more bottle feedings over time.
Try offering the cup at different times of day, let them play with it first, or fill it with something they already enjoy like breast milk or formula. Make cup drinking fun and pressure-free—forcing it often creates resistance, so stay patient and keep offering it without stress.
