Nah, that would take longer. We have the water in a pitcher on the counter so it's just pour & scoop & shake - no warming necessary.
AGrates:I make bottles for the entire day. All set to go, just have to be warmed when ready. so much easier than making for each feeding
This is what I do too. I make them the evening before, once both kids are in bed. That way they're all set and ready to go for the next day.
