So the boys are 4.5 months old, adjusted age is about 11 weeks.
We do a bedtime routine starting at 7pm, they are in bed and usually asleep by 8 (it takes one a long time to fall asleep and the other almost an hour to eat a bottle). Then they usually sleep and then start waking up anytime between 1 and 3 for the first night bottle. Then again around 5 or 6. They sometimes wake up an hour apart. DH has the second shift (from 1 am-7am, I get up at 5:50 to get DD ready for school). He says they often stay awake for a couple hours or just keep fussing between bottles. They nap during the day but not consistently. We often spend most of nap time running back and forth upstairs to put nippies back in.
What would you do? Say all the wake up times after their six hour sleep chunk are normal? Wake them both up to feed them whenever the first one gets up? something else? DD was an awesome sleeper and by this age was going for 12 hours straight with consistent naps. What do we do? any ideas?
Re: sleep question
We usually feed around 7:30, in bed by 8 and A usually wakes up at about 1 and between 4 and 5. We always wake up O to eat at the same time. For him it is a dream feed, but that's the only way we can do it and not be up all night because I'm sure he would be up within the next hour. If either is awake when they are supposed to be going back asleep, I will rock them for a few minutes, put them down in the crib and then leave the room. They are always asleep within a few minutes.
Nap time during the day is a different ball game. They almost always nap on opposite schedules and only for 30 min-1 hr at a time. But still we always feed at the same time.
Anything before 6 (or possibly 7) I would treat as a night waking. Whether you feed together or separately depends on what works for you. What we used to do was feed one right after the other at night b/c if we fed them at the same time, they would get too awake/worked up (e.g. during the interruption while waiting for us to go get brother, change his diaper if needed, put him in his bouncy seat, or when stopping to burp the other). But we would wake the second and feed him right away to keep them close to the same schedule and then get back to the same schedule afterward.
We did find their sleep was a lot worse from 2 or 3 until about 7 or 8 a.m. and another MoM on this board finally helped me figure out it was from reflux. From 2 a.m. on can be the "witching hour" for reflux b/c even if it's otherwise well-controlled, being on their backs for so long can make it worse. We had them start sleeping on an incline and within 3-4 weeks of that change, they were STTN.

Pretty Normal for them to still wake between 1-3 at 4 months. I have one who was still waking at that time till around 5 months and one who was sleeping 11 hours at night by 3.5 months. I stopped waking the good sleeper when I could tell she wanted to go longer. Also, mine are up for the day between 5-6 so to me it looks like your girls are really only getting up once at night which is pretty good. I'm guessing they will stop waking between 1-3 within the next few weeks.
Also, about that age I tried binky replacement and sooth before feeding a bottle. If they couldn't fall back asleep I know it's hunger. 4.5 months was also a pretty big growth spurt around here.
