Powdered Formula

Hello fellow POMs! My girls were born at 36 weeks and are now a month old. We’ve been using ready to use formula and would like to switch to powdered formula. I’m a FTM and I’m getting conflicting information from my research. Would love some advice! Please pardon any typos. I’m so tired.

  1. The nurse practitioner said switching to powdered formula is fine but google suggests we shouldn’t be doing this yet since the girls were born early. I am slightly concerned that I had to keep reminding the NP throughout the appointment that the girls were born early. If your kids were otherwise healthy, when did you make the switch?

  2. How the heck do you prepare powdered formula?! There is so much conflicting information regarding whether water should be boiled. Are we boiling water? Using distilled or nursery water? (Is there even a difference between distilled and nursery?) If water is boiled and cooled, is it mixed at a warm temp? can the formula still be served cold or is it supposed to be heated back up? My girls are used to bottles straight from the fridge and we’d like to keep doing that. I’m hoping it’s just the exhaustion but I literally cannot wrap my mind around the steps to make formula. Please explain it like I’m missing a brain.

  3. How do I do powdered formula on the go? Are we making it in pitchers at home and keeping it cold? Are we literally taking powder and water and mixing it out and about?

This is a lot but I’m so overwhelmed trying to figure out the formula situation. Thank you in advance for your input!
