DS is 6 months and I ebf him until he was 18 weeks. Now he gets formula during the day as I'm back to work.
When we go out and about I used to take a sterilised bottle and a ready made carton.
Now cartons have increased in price from 47p to 60p in a week!! WTF 
Anyway, how do you make up bottles with powder? Can you used pre boiled water and powder in a dispenser thingy? I know formula has to be made with water over 70 degrees but does it matter if he's 6 months and it's only now and again?
And if you just ask for boiling water out, how do you cool the bottle?
I do feel silly asking seeing as I if we're in a coffee shop I'll spend over £2 on a latte
.
But I need to know the answer just incase I run out of cartons for whatever reason.
I'd say I'll still use them out of convenience though :)
