Making bottles out and about

I use the Nuby rapid cool and a hot flask, I do the hot shot method so I don't need to worry about washing and sterilising

I fill up 2 or 3 bottles up to about 3oz with boiled water before I leave then fill up a thermal flask ( just my water bottle which stays hot) with boiling water and top up the bottles when out to make a feed x

I use the Momcozy bottle warmer when we go out and Nuby rapidcool at home. I prefer using the bottle warmer whilst out but using the ready made bottles of milk that are at room temperature so it heats up quicker. It’s not as quick as doing hot shot with rapid cool and powder formula but I find the bottle warmer and ready made formula takes up less space in my bag so I prefer it currently
