Please help me settle a formula argument.

ladiebugg1 · June 2011

Arguing with my MIL, and it is really starting to tick me off.....

Using powder formula, we usually use 4 oz of water and 2 scoops of formula. Once the bottle is made, it is about 4.5 oz. If LO drinks the entire bottle, would you say he ate 4 oz because that is the amount of formula you used, OR he ate 4.5 oz because that is the total volume after mixing.

TIA

I say 4oz but really it doesn't matter either way!

I always say she had a 4 ounce bottle, but I know it's about 4.5.

I got by total volume, not including the bubbles at the top.

bre87 · June 2011

i go by water poured in, so 4oz.

What EmJay said.

plus - EmJay your daughter is 100% adorable!

I'd say 4.5 based on when I spoke to Similac the helpline said that when add water to the mix it actually makes more. Like if you were making 8 oz it'd come out to be 8.5. So then if you wanted LO to have 8 oz you'd throw out the .5 Tell us what happens!

I go by total volume as well, I use the formula pitcher for 99% of feeding so I have to count it that way.

This. Hmm

4.5 oz bottle

Go by this. If you were using breastmilk, ready-to-feed formula, or formula mixed with a formula pitcher, how much would you pour into the bottle?

If your LO drinks the entire prepared 4oz. bottle with formula - would you short them the extra .5 ounce that you would have poured if you used the method above? Nope - you would pour a 4.5 oz. bottle.

I would say 4.5.

DD drinks 6 oz. I usually put the powder/rice cereal in first then fill with water to the 7oz mark. Once I shake/mix it is 6 oz.

NewFamily09 · June 2011

I guess I would say 4 oz, because when you shake it up and it goes up to 4.5, some of that is bubbles. I'm trying to remember back to when DS1 was FF and I think that's what we'd go by.

It's absolutely a 4 ounce bottle because what you're actually attempting to track is the amount of liquid the baby has consumed. When it reads 4.5 that's because of displacement. If you filled the bottle with 4 ounces of water and then dropped a marble in it, it jumped to 4.5 and baby drank all the liquid, how much liquid did s/he drink? 4 ounces

For the poster who said if you were using BM or milk you'd count it as 4.5 that's right because in that case there is no displacement. It would literally be 4.5 ounces of liquid if that's how much your poured in.

. No, you're tracking the amount of formula consumed, not water. There was displacement with ready-to-feed formula too, it's just that you don't see it bc it was done at the factory. So OP, go with final volume. In case anyone cares, formula powder generally displaces 0.7ml of water per gram of powder, but the caloric density is based on final, total volume.

Thanks for the opinions...It matters because LO didn't gain any weight since his last pedi visit (about a month ago) so the doctors wants me to start tracking how much he eats everyday. We've been feeding on demand, so we are wondering if he is eating about the same amounts each day.

bumpuser260585 · June 2011

We had weight issues too, so when we switched to formula I asked the pedi how to"count"it amd she said to count the amount of water we put on the bottle. So, per my pedi, i'd count it as 4 oz. You could always ask your pedi at your next check up.

You do realize you're supposed to put the water in first, right?

Well, I disagree The amount of actual formula you put it is the same whether you say the bottle is 4 or 4.5 ounces - you put in two scoops. So if they literally wanted to know how much FORMULA the baby was eating, they'd have you report how many scoops the baby is eating in a day.
