Three types of prepared infant formulas are available:
1. Powdered formula is mixed like instant coffee. A scoop of powdered formula is added for each 2 ounces of water and stirred.
2. Ready-To-Use formula comes in small disposable bottles and quartcans. It needs no preparation and is very convenient, but more expensive than concentrated liquid or powdered formula.
3. Concentrated liquid formula comes in 13-ounce cans and is prepared by adding equal quantities of concentrated liquid formula and water from the tap.
4. Most tap water is safe for mixing formula for your baby. If you use bottled water, we recommend that you buy water with fluoride added.
