I didnt realise there was so much contraversy surrounding making up formula
You boil the kettle only once, you leave it to cool for no more than half hour, poor into clean/sterilised bottle and you put the correct amount of formula in. Shake, check temp, run under cold tap if needed and serve...
or
You do above (without serving), then store it in fridge up to 24 hrs no longer, then you can reheat in microwave (yes you can), shake and test temp with temp food probe has to be above 70'C, then you allow to cool by placing in cool water. Then serve...Never reheat twice, never leave made up formula out for over two hours...I never left is more than an hour.
Boiling water should never be put into bottles that arent BPA free - risk of chemicals dispersing is high. Throw scratched bottles away. Dont use teats for more than 3 months.
For those dumb ppl who use tap water straight from the tap- Never use tap water straight from the tap!!!!
I was gobsmacked teeny when I read your thread...its just sickening literally.
Bottles can be sterilised up to 6 months of age - some mums dont bother at all - yuk - or even better up to 12 months.
You will find all info here at FSA think teeny you should make some posters and stick them up in the public loo's
