Which formula is best?

Most formulas are about the same nutritional-wise, although various brands can affect your baby differently, so discuss formula brand choices with your pediatrician. That said, when it comes to formula type choices you have three choices - powdered, canned or other ready to feed formula, or liquid concentrate. Ready to feed formula pros and cons:

• Totally easy; you pop it open, pour into a bottle, and feed.
• No mixing or measuring so saves time.
• Costs the most (usually) of any formula type.
• Can only be stored after opening for 48 hours.
• The cans or bottles of ready-to serve formula are bulky and take up valuable kitchen real estate.

Liquid concentrate formula pros and cons:

• You'll have to add water, but it's less trouble that mixing powdered formula.
• Once mixed, can only be stored 48 hours.
• Cans are large, heavy, and take up kitchen space.

Powdered formula pros and cons:

• Costs the least of any of the formula types (usually).
• Powder stores easily and safely for a month, which means less waste.
• Mixing can be tricky and powder can clump in the bottle or spill easily making a powdery mess in your kitchen.
• Not very travel-friendly.

Also if you're feeding your baby with any formula, make sure that you aren't making common formula safety mistakes.
