If you're using formula you can also make the sterilised bottles up with just boiled water in & they will stay sterile for 24 hours. Then you can just grab & put powder in when needed.
This is how I have made my bottles up for the past year. The healthcare assistant at my hospital told me that I could do it like this. In nearly a year, my lo has been fine with me making his bottles like this.
things change over the years, when i had my first 10 years ago we was told to make up the feeds for the next 24hrs and keep them in the fridge and heat when needed and it never hurt my son, when i had my 2nd son 4yrs ago the advice had changed again it was make fresh feeds as you go not in advance!!
i asked HV and she said the advice had changed as there were many parents who did not store milk proprly after it had been made and was making their children ill, she said it was still ok to do as long as you do it properly i.e make feeds up, cool down in water, put in fridge, reheat when needed so this is what i did then but ony i made them up on the morning for the day ahead and then again at nite to get me threw the nite!!
3rd time around i do it how i did it for my 2nd child
making feeds up in advance has never hurt any of my kids, and im not prepeared to make him starve by sterilising botte, boiling kettle making feeds and cooling to the right temp as he feeds on demand so feels its unfair to let him scream and cry for 30 mins plus each time for a feed
the water thing is ok as long as you heat the water up before you add the milk, and clearly everyone has their diff ways of making up formula and all of them have more than likely been the right way to do it at some point or another else we wouldnt do it xxx
