  4. I ordered the Itsy guzzler after parttimeworkingmummy showed your products on her page. Wow!!! What a simple but incredible little gadget, I wish these were available when I had my first baby 3 years ago. It will be amazing for holidays, days out etc and so handy to keep in the baby bag. I love the idea of not having to take sterilised bottles wherever we go. Thank you so so much. 100% recommend to anyone with little ones xx

  5. This is a great little product for when you are out and about with a little one. My toddler loves juice cartons but has a tendency to squeeze and also to lose the straw! This simply screws on and provides a sippy spout. Just be careful not to screw it on too tight.

  6. This is a brilliant product. My son is just 1 and wants to be like his big brother and drink out of juice cartons or water bottles but ends up covered in it. The sippy cup teat guzzler allows him to drink whilst out and about without making any mess.
    We would definitely recommend!

  10. Itsy Guzzler – Sippy Spout
    Great product – makes life so much easier going out and about with just a ready made bottle of formula and not having to also take a bottle to pour it into.

Forgotten the milk or juice for the little one? Fear not – our ground-breaking Itsy Guzzler adapts most formula bottles and juice cartons into child and baby friendly drinks. With 3 individual screw fittings, the guzzler fits formula bottles, juice cartons and even most standard water bottles!

Choose between three sizes – slow, medium, fast flow and a free-flowing “Sippy Cup”  spout too. Our Itsy Guzzler is also interchangeable with other branded standard neck teats if you just can’t live without them!

With its pod cover lid you can take that milk, water or even juice with you on any adventure!

Teats supplied with the Itsy Guzzler are great for the following ages:

  • Slow Flow – Great for babies aged 0-3m.
  • Medium Flow – Great for babies aged 2-4m.
  • Fast Flow – Great for babies aged 3-6m.
  • Sippy Cup (free flow) – Great for babies aged 6m+.

Please remember that these ages are only a guide. You know your baby better than anyone and will be able to tell when they’re ready for a faster flow.

Formula bit

This useful little part can be screwed directly onto the thread of 200ml pre-made formula bottles all over the world (trust us, we’ve checked!) from brand such as Aptamil and Cow & Gate here in the UK, and Nutricia and others abroad.  Simply unscrew the other two pieces and keep them safe and you can turn a pre-made formula bottle into a baby bottle in an instant.

Water bottle bit

Leaving the middle part of the Itsy Guzzler adapter screwed in place gives you a handy screw collar that can be attached to most major water bottle brands, including Evian and Volvic, and many more available around the world.  Handy for adventures anywhere away from home, or simply to keep spills to a minimum at home too!

Juice box spike

This handy spike is designed to be screwed into the straw hole of any juice box available around the globe. When screwed in, it forms a water-tight seal (it’s been tested to British Standards to ensure this is the case) and turns a regular juice carton into a sippy cup for your little one.  The leak-proof seal is good for 24 hours, and the pod cover can be used to take a half-finished carton with you.  No more squirting straws the moment you hand over a newly opened carton!

Pod cover

We supply a pod to house all the adapter pieces together so you can carry the Itsy Guzzler around with ease.  Plus, they double up as a cap for an unfinished bottle too to keep spills to a minimum.

We’ve even included a QR code on the box to show you how to use it and to show you what it’s compatible with.
