Are Philips Avent straw cups compatible with other Avent products?

The Philips Avent straw cup is compatible with both the Philips Avent Natural and Classic+ bottle ranges (excluding glass bottles), as well as our complete cup range (excluding the My Natural Drinking Cup/Grown up cup). Our complete range is designed to support your child and you at every step in the journey towards independent drinking.

The straws are not compatible with straws of earlier straw cup ranges.
