Babies typically start holding their own bottle around 6 to 9 months of age. This range can vary depending on individual development factors like arm strength, fine motor skills, and hand-eye coordination. Some babies may begin a little earlier or later than this window, and both are normal. Even when a baby starts holding their own bottle, it is important to supervise them during feeding to ensure safety, as they may not be able to fully control or hold the bottle securely yet. The American Academy of Pediatrics also advises against propping a bottle to let a baby feed unattended due to risks like choking or ear infections. Around the same time frame (9 to 12 months), babies usually start to hold a cup with both hands and bring it to their mouth, progressing to more independent drinking skills by 12 to 15 months. In summary:

• Babies start holding their own bottle: approximately 6 to 9 months
• Supervision is necessary during bottle feeding
• Progression to holding and drinking from a cup starts around 9 months and onwards

This milestone is part of many physical and developmental achievements as babies grow toward self-feeding independence.
