FF mum gets up, goes to the kitchen, gets the bottle, heats up the water, mixes the formula powder in (which has to be exact), feeds baby, puts baby back to sleep, back to the kitchen, rinses the bottle, back to bed. You have to be totally awake to measure of the formula or you're in trouble & it takes longer to get back to sleep from fully awake.

So yep I definitely agree with the study!

As a Mum who FF, I have an avent cont that keeps the correct amt of formula in it ready to go at night, I have never heated the bottles it's not actually necessary & it's harder when out if you can't heat a bottle & that's all bubs is used to. So I have the bottle & cont with formula on my bedside table (no need to go to Kitchen), mix it, shake it when bubs wakes up then feed. I'm done & in bed back to sleep in less than 15mins...he scoffs his night feed. We have a recliner & I close my eyes & doze whilst feeding. And I'm lazy, the bottle gets a good wash in the morn, not that night LOL.
Yes I agree with what the study is saying, just wanted to point out that if you are organised etc it's not such a huge task at night time. And if bubs is in own room regardless of BF or FF you still have to get up, get bubs & regardless of how bubs is fed they always have to be put back to sleep. Doing it on their own or not is a different story.
