I use the nuby all the time even at home!
I moved onto combi feeding and would be lost without the nuby for days out! I got the double pack with the flask on Amazon for a good price
I just make one or two up with boiling water before i go out, depending on how long ill be.
Ready made formula or take a bottle you’ve made out with you and heat it up when you need it - but I find taking a sterilised bottle and ready made formula easier
Definitely makes bottle making on the go easier and I would use it at home if I didn’t get the prep machine. I use the hot shot method so I can keep using it in the day without sterilising it. I’ve seen Aldi have them in there next baby event for £19.99 which is a great price x
