If it’s just the night she may play catch up by shortening the times in the day. When my son was sleeping longer in the night his day feeds became every 1.5-2 hours. If there’s nothing wrong with her weight i wouldn’t wake her she will let you know when she’s hungry x
As long as she’s back to her birth weight/above, I wouldn’t wake her. She will wake if and when she is hungry, so make the most of the sleep!x
If she’s back at her birth weight then I personally wouldn’t wake her and enjoy the extra sleep
