DD1 had blessedly started sleeping through the night but is now waking up at 5am, having a giant poo which requires full changing (clothes, linens, etc.) and then not going back to sleep. This morning by 620 I finally figured out she was ravenous. She does wake up at 1 and 3 but settles herself back to sleep so I haven't been feeding her. But I'd rather feed her at 3 and have her settle back to sleep than be up this early. Should I go back to feeding her at 3? Or persevere and hope she eventually stops waking at 5?
