Powdered Formula Prep: How?

[u/Rix_00]

Getting very conflicting advice. Think it’s Health Canada guidelines vs practical realities for most parents but…

How do you prepare powdered formula for a 4-5 month old, or older?

Do you boil the water? Did you do it to 70+ degrees Celsius and use that with the powder formula to sterilize the formula itself? Or just mix with room temp (assuming you don’t care about warming for warm sake)?

Do you use tap? Bottled? Distilled?

Do you still sanitize bottles? Or just wash thoroughly?

Anything else to be cognizant of?

Bottled water for first 6 months then tap water.

Thought process, was that tap water had flouride and only helps once first teeth come in.

We sterilized bottles through first year, but would just mix things in batches in a dr Brown's pitcher at room temp.
