Help with using the Nuby rapidcool

How much hot water have you put in? We found we had to put at least 4oz in for it to register

I’m attempting the hot shot method, my LO is on 4oz so I’ve only put 2oz in the Nuby

We put the full amount of hot water required in to ours (210ml), then add the powder, shake vigorously for at least 60 seconds and then check the top has gone green, i always check temp on my wrist aswell. We have been using this method for 6 months with no problems.xx

Not sure if there is a newer version but I didn’t think there was a button? I used to add formula to the bottle and total amount of boiled water, shake it up, pour it into the Nuby then leave it upside down until it went green (make sure the liquid is in contact with the lid as that’s where the temp sensor is)

but wouldn’t doing it this way mean you’d have to keep sterilising the Nuby? (I only have one so I’m trying to avoid having to keep sterilising it!)

no there isn’t a button but I just meant that I’d tap the top of the bottle and it would go green literally straightaway, I didn’t think it could cool down water that quick

We’ve had the exact same issue! I think maybe it’s not enough liquid for it to register. I’ve given up with the nuby rapid and now make bottles this way which has been a game changer, can’t believe I didn’t think of it before 😂 https://vm.tiktok.com/ZGekKWkh4/

Keep it upside down so the water still touches the lid when you press the button and shake occasionally too, so it's an even temp all over x

Putting 2 ounces of hot shot in and 2 ounces of water from the Nuby will be too hot for the baby. I tried with 6 ounces (2 ounces hot shot and 4 in the Nuby and took the temperature and it was still near on 60 degrees) so at only 4 ounces and 2 being hot and 2 being in the Nuby it will be way too hot. I would just use it and clean and sterilise it the way you should for the time being at least until the baby is taking a bigger feed and you can make a cooler bottle. Or simply boycott the Nuby for now and do 1 ounce of hot shot from the kettle and fill a bottle first thing with boiled water and put this in the fridge. Then add the remainder of the ‘cool’ water from this to make the bottles. It’s just as easy as using the Nuby tbh.

@incognito we wash ours with hot soapt water after every use and sterilise the seals once a day.xx
