Each baby is different.
I Ditto Dori W. below.
A baby/newborn- wakes, cries, feeds. The parents get less sleep. It just is.
What worked or did not work for one baby, will be different for another.
Both my kids were so different from each other. And they had GINORMOUS appetites and I was nursing. I went by their cues.
Also keep in mind, that a newborn needs to 'bond.' And bonding is important for their development and brain development too.
Each baby, having different personalities and needs.
There is no single 'right' method.
But knowing your baby's cues.
Some babies, with crying it out, simply have "learned" to give up. That is why they stop. It gets them nothing.
You also have to discern, that a baby waking or crying, maybe simply needs to feed. Feeds can even be every single hour. ie: cluster feeding.
So feed on-demand.
A baby this young, will not have a pattern or schedule of sleeping. Yet.
Many babies also fall asleep in the parents arms. Because, it is soothing and comfy. AND, a baby, was used to being "cocooned" in the womb.
In a small space.
Also, babies commonly wake/cry/make noises when sleeping. So, "discern" the type of 'cry' she has. If it is hunger/or needing you. For my kids, I KNEW their cries. I also knew, if it was just a transient noise-cry, they made as the slept. Or, IF they were not awake-awake, but just making noises, I did not disturb them. Otherwise, I would just be disturbing their sleep and actually waking them. Instead.
So, 'discern' your baby's cries and noises.
And hopefully she is napping.
If not, over-tiredness makes it harder for a baby to fall asleep.
Also, too much stimuli, before sleeping, can prevent them from being able to sleep.
At this age, even a bath, is a major activity.
Babies, usually get tired and need a nap/sleep, after being awake for about 2 hours.
She is pretty normal for a newborn.
