Product Components
Your Nuby 3-in-1 Baby Bottle to Training Sippy Cup includes the following parts:
- Bottle Body: An 8 oz (240 ml) clear, durable, and lightweight bottle with liquid measurement markings.
- Soft Flex Silicone Nipple (Vari-Flo): Designed for early feeding stages, featuring teething nubs to soothe gums.
- Soft Flex Spout: For transitioning to a sippy cup, providing a spill-proof drinking experience.
- Removable Easy-Grip Handles: Textured handles for comfort and control as your child learns to hold the cup independently.
- Lid/Cap: A protective cover for hygiene and spill prevention.
Assembly and Transition Stages
The Nuby 3-in-1 system is designed to adapt to your child's growth. Follow these stages for optimal use:
Stage 1: Baby Bottle with Nipple (3+ Months)
For infants, use the bottle body with the Soft Flex Silicone Nipple. The Vari-Flo valve allows your child to control the flow rate, and the teething nubs help massage and soothe gums.

Stage 2: Baby Bottle with Nipple and Handles (6+ Months)
As your baby grows and develops motor skills, attach the removable easy-grip handles to the bottle. This helps them learn to hold the bottle independently while still using the familiar nipple.

Stage 3: Training Sippy Cup with Spout and Handles (6+ Months)
When your child is ready to transition from a nipple to a spout, replace the silicone nipple with the Soft Flex Spout. Keep the handles attached to provide stability and encourage independent drinking from a cup.

Stage 4: Sippy Cup with Spout (Older Toddlers)
For older toddlers who have mastered holding and drinking, the removable handles can be detached, allowing the cup to be used as a standard sippy cup.
