If she's above her birth weight then it's absolutely fine to leave her she obviously needed the sleep and she will wake when hungry. It's so hard to begin with I'd panic waking up but my 16 week old has slept through 9 hours since around 10 weeks. Enjoy the sleep. You're doing amazing ❤️
Thanks both 💕 feeling relieved now!
If she’s above her birth weight you can leave her to sleep for as long as she wants. She’ll feed when she’s hungry. At 6 weeks my baby was sleeping 10 hours x
