| my twins are now 4 weeks old (just hit their term date today infact!). I HAVE fed them together, but only when they have both been screaming for a feed. Otherwise I feed the one that wakes first and then the second. Both are pretty good feeders, although one is less windy than the other so takes less burping.
I feed them every 3 hours during the day, last feed being 10pm and then 4 hours during the night (so at 2pm, and 6am)...unless they wake earlier. Once they get to 6 weeks old I will stop waking them at 2am and just see how long they can go in the night....but if one wakes I shall then wake the other as don't want to be getting up several times in the night.
I have based my 'routine' on the Baby Whisperer's (Tracey Hogg) which worked really well for my first.
All in all a feed for both inc burping and changing takes an hour.
I've currently got mastitis and it was very painful for me to feed from one of my breasts so I have now switched to bottles of expressed milk. While this means I have to spend extra time pumping, it does mean that someone else can give the feeds (ie the maternity nurse during the night so I get more sleep), and I can also spend more time during the day with my toddler.
Hope this helps, and good luck with your pregnancy...mine was horrid!
