Have been breast feeding but baby is not getting enough so now have to combine feed. When I did it years ago, water could be prepared earlier but now everything has changed and it has to be fresh and 70 degrees. How do you quickly prepare formula fresh in the middle of the night? I don’t think baby would wait 30 mins for water to cool. I don’t want to get a prep machine as I’ve been told they are not the best. Thank you 😊
