Not brilliant here either. She went down at 7:30pm and woke herself at 9:30, so we gave her a bottle then. She was up again twice in the night so she hasn't remembered how to sleep through just yet.
Not that twice up in the night is bad, but she was doing really well before this blip so its just a shame thats all.
IMO, if your LO's yawning and giving you all the cues that she needs naps. And also if she's beginning to start napping for longer then she obviously needs it during the day.
I was told to never let a baby nap longer than a feed cycle, which for my LO is 3.5 - 4 hours ish. I'm not sure whether they meant all in one go, or that the naps during the day should not add up to more than a feed cycle? But the latter seems to work for DD. She has roughly 3.5 hours of sleep during the day.
I think the wakefulness during the night and the waking up is just normal right now. I'm sure they'll get the hang of it. I read that you should try not to immediately feed when they wake at night and try to settle them down (like you said you did with the dummy for your LO), but then if nothing else works, then feed them. I must admit I don't really do this, I normally just click into autopilot and assume she wants food. But last night she woke at 2am after her bottle at 10pm and I know she can sleep further than 4 hours on a bottle. She's managed 9 hours straight before, so If she can do once, I guess she can do it again. I'll have to start trying to settle her down during the night if she wakes.
