Why does the nipple collapse during feeding?

If the nipple collapses during feeding, the anti-colic vent may be blocked by dried milk, creating negative pressure. To prevent this, gently squeeze the vent area inside the nipple before each use to ensure it's clear and allows smooth airflow.

Why don’t the 0M+ and 3M+ bottles come with handles and gravity ball straws?

Babies 0–7 months have immature lungs, and early straw use may strain their sucking. Their hand strength is also limited, making it hard to hold a full bottle or grip handles securely.
