Yeah, if you want her in bed at 7pm...which is a good time since your other lo's are in bed then, you'll need to get her up at 7am.
-5am should not be considered the first feed of the day since she is eating and going back to bed. Plus you honestly don't want your day to start at 5am
That should be considered a night feed.
If you first feed is minimal with a 7am wake up, it's always a sign that that 5am feed needs to start cutting back as you want them to get most of their calories during the day....and you don't want day time feeds to be small due to a night time feed.
You can just start to put less and less calories in the bottle yet still have the same amount of ounces....just add in extra water....until you are left with just water and that first feed is nice and full again.
