Which NUK cups are these replacement nipples compatible with?

These replacement nipples are made to fit NUK Active and NUK Learner cups – they go on snug and stay put. If those are the cups you have at home, you're good to go.

Is this nipple durable enough for teething babies who like to bite?

This nipple is made from flexible yet tough silicone – it holds up well to chewing and keeps its shape. That said, teething babies can be pretty determined, so having a few spares on hand is never a bad idea.

Does this replacement spout leak?

This spout features a dual-line cut that helps prevent spills, and the air vent balances pressure inside the cup. If your little one chews it out of shape, it may not seal as well – just keep an eye on it and replace when needed.

Is it easy to clean? Can I use a dishwasher？

Super easy – pop them in the dishwasher without worry. The silicone doesn't hold onto smells, and they come apart quickly for a thorough rinse. No fuss at all, even with daily use.

Does this nipple help with the transition from bottle to cup?

The soft silicone feels familiar to babies who are used to bottle nipples, so they're less likely to push the cup away. The vent also makes sipping smoother, giving them a gentle nudge toward drinking on their own – one small step at a time.
