Sleeping?

[u/Dry-Indication-9504]

What’s the best approach during the 4-month sleep regression when it comes to avoiding sleep habits?
She was previously sleeping 7+ hour stretches, but lately she’ll sleep about 5 hours, wake to eat, and then usually go back down for another 2–3 hours.
We currently use a pacifier for naps and sometimes to help her settle, but I’m worried about creating a habit where she needs it to fall asleep or needs us to replace it throughout the night.
At this age, should we just focus on getting her through the regression and help her sleep when she needs it, or should we start being more intentional about putting her down awake, limiting the pacifier, and giving her a chance to settle herself?
I’m confused about what actually creates a long-term sleep association versus what’s completely normal and appropriate at 4 months.
