Hi all. New mum here baby is two weeks tomorrow. We have been using the pre made cow and gate milk since we left hospital but now have tubs of the cow and gate powder. It says to boil the kettle and make as needed... does anyone pre make the water during the day and just add the formula before the feed... babies don’t want to wait 30 mins for the water to cool they want feeding now lol. Advice please?? My friend said she boiled enough bottles in the morning and added the formula before the feed... yet my sister in law says you need to do it all there and the meaning a long 30 min wait for water to cool?
