Two cups in one for babies starting solids. With the lid on, the soft valve-free silicone straw teaches real straw drinking – your baby draws the liquid up themselves. With the lid off, it is an open cup for supervised practice.

The weighted, tapered base resists tipping while staying light enough for small hands to lift, and the translucent body lets you see how much has gone down.

Frequently asked questions

Is this cup spill proof?

No. It is spill-resistant with the lid on, but the straw has no valve, so it will leak if tipped or shaken. With the lid off it is an open cup by design.

Why doesn't the straw have a valve?

Without a valve your baby has to draw the liquid up themselves, which is the straw-drinking skill they are learning.

Can I buy a replacement straw and lid?

Yes. Olababy sells the lid and straw together as a replacement set.

When should we move up to the 9oz cup?

From 12 months, once your child regularly finishes the 5oz cup in one sitting.
