I know the advice is to not to, and make it fresh, but its not always practical.
The cartoons can be expensive, so I'd like to avoid using these.
People have advised one of two ways of pre making formula, but I'm not sure which one to go for.
1). Pre prepare the formula as per instructions on the box, and put the bottles in the fridge. Then heat up as and when its needed.
2). Prepare the water part only, leave this out at room temperature. Then, when you need to make a feed, just add the powder and serve. (this is the method I use when out and about, as I can carry the formula with me pre measured.)
Which way should I go for when at home?
