Got a few thoughts for you
Today we managed to go 3.5 to 4 hours between feeds all day and didn't feed at all before sleep. All her sleeps today were 2 hours.
That's great progress! IMHO, I would try to stick closer to the 3.5h end to start, especially since she's ebf and no solids yet. She's used to having her tummy filled every couple of hours, so to suddenly jump to every 4h can cause dehydration (not common, but it has happened!) as it's too big of a change too quickly. Sticking to around 3.5h for a while will give her time to adapt to taking bigger feeds less frequently.
We don't do a dreamfeed.
At present I find she is feed once or twice a night.
That's no problem, some los don't take to the dreamfeed, and in others it can really disrupt their sleep (as you've found!).
Night feeds are definitely hard, especially when you had that stretch of time with no night feeds at all. At this age feeding at night is still reasonable, especially for an ebf lo. Without a dreamfeed, 2 night feeds is not uncommon. My ds did a dreamfeed and a night feed until around 8-9mo. Have you read
http://babywhispererforums.com/index.php?topic=98183.0? It won't ease your fatigue, but there's some really good information on there about night feeds, and includes a link on weaning night feeds if you decide that that is something you would like to do.
It all depends when she gets up (based on when she feeds in the night), whether she is hungry first thing (often she isn't if she has fed at 5am), if we go out etc.
It's normal for them to not be hungry enough for a full feed if they fed in the wee hours of the morning. Can you get her to latch on at all? The goal really is to get her to take a 'top up' feed; enough to fill her tummy so she can last to the next EASY feeding time and keep your routine on track.
Have you ever tried a set wake up time with her? That's another thing that keeps your EASY on a better track and helps you plan your day if you do have to go out. When my ds was younger, I found that any wake up time later than 730 really threw our day for a loop. I would wake him by then if he was still sleeping and our days were much smoother.
S 4.00 - 4.45
E 5.30
E 6.30 (often on 4 times before she will settle)
S Often 8pm before she has finished wanting the breast and goes to sleep.
I think that your dd is really OT at bedtime, and is possibly using you as a pacifier to settle herself for that reason. If she was up at 630am, you really should be aiming for a 630pm bedtime for a 12h day/night. Do you have a bedtime routine with her? Have you tried feeding her earlier, knowing that she's going to want to feed a few times before bed? Our milk supplies are at their lowest in the evenings, so she could be hungry and tanking herself up, but I do believe that OT could be a big factor too. I would try an earlier bedtime for a few days and see if that helps.
What do you think?
