SPOUT: Great for babies (4M+) starting baby food early.
WEIGHTED KIT: Helps babies (6M+) drink from any angle while holding the cup.
STAGE 1 STRAW: A super soft straw (6M+), made from the same material as baby nipples, helps babies transition to straw drinking comfortably.
STAGE 2 STRAW: A firmer straw (12M+) for older babies. The flow is the same as Stage 1, but the silicone is stronger. Switch to Stage 2 when babies start chewing more.

How do I choose the right cup size?
If your baby is new to straw cups, the shorter 200ml size is often easier for them to handle. For basic use like water or small quantities of liquids, 200ml is sufficient. If your child drinks more or if you plan to fill it with milk or other beverages, a 300ml cup is recommended.
