I have been breastfeeding for the past 6 months and my baby has just started on bottles of formula. We live with my parents at the moment while we are waiting for the house that we are buying to be ready, and my mum uses the kettle constantly during the day to make hot chocolates, so this is what we have been doing:
Boiling a kettle full of fresh water
Pouring out 120ml into each bottle
Leaving them on the side with lids on
Measuring out formula into pots
When baby is hungry, we just tip one of the pots of formula into the water, shake and feed. He doesn't seem bothered what temperature they are at and is usually fine with them at room temp.
Is this okay to do? Obviously because he has been breastfed for the last 6 months I have never spoken to a HV or Doctor about bottles etc!!!
