I started 4hrs yesterday. Are you saying to go back to 3hrs45 or just be consistent with one time for awhile?
If you started doing 4h then great, stick with that for a while.
So she still woke at her normal 5ish. With loosing so much sleep last night should I put her down earlier for her nap?
I would follow her cues, some babies can handle normal A after short nights (DS was like that).
Is she waking up every night at 5? Could it be habitual?
Before the last two weird nights of multiple wakings when she woke at 5 she would fuss for a few mins then chill. I tried nursing her right when she woke and also after she was hanging out for 30-40 mins. Same results- up for at least an hour.
That sounds like a typical UT NW.
When they get chronically ot do you encourage to pull back on awake time or just keep the course and hope she can make up for sleep at night?
When CHRONICALLY ot I would do 1-2 days of catching up on sleep, AP or offering as much sleep as possible, even if it's just 40min naps, but to have loads of those, and then go back to the previous A time and stick with it.
You can of course go for EBT to give her an opportunity to tack. Not all babies do that, but many. And it doesn't work in one night, you need to give like 3-4 nights to see if EBT is working.
But if I nurse will she expect it and make it a habit?
Of course, if you are going to do it for a while, not once in a while. I start to think that this is also what is happening at the 5AM NW... I think she got used to eat then and needs it to go back to sleep.
