I wouldn’t wake her if she’s above her birth weight x
Once they're beyond birth weight and not jaundiced (not all, but a lot get this) you can allow them to sleep as long as they'd like essentially. Enjoy the sleep while you can mumma.
My ebf girl started sleeping through the night at a similar age, she would cluster feed in the evening before bed and was above birth weight with no weight/feeding concerns so I left her to it and enjoyed the sleep whilst I could! (She stopped sleeping through at 4 months). Engorgement used to wake me up at 5am so I would pump for comfort and my supply wasn’t affected when I started doing night feeds again.
Once they’re above birth weight, you’re good to let them sleep! You’ll probably find you’ll have peaks and troughs of sleeping through so I’d take the sleep wherever you can x
100% enjoy that rest mama
I was told that once they get back to birth weight and are gaining well that you can leave them, she's probably getting enough through the day she's not hungry at night. Let yourself enjoy some longer stretches of sleep!!
