Babies of around one year old are often active by day and wake frequently at night, for no obvious reason. Then a mother can feel desparate for sleep yet equally desparate to comfort her baby when he needs her at night. I have spoken to many mothers who have sacrificed their own sleep, waking up numerous times every night because their babies cried for them. It seems terrible that these hardworking women think of themselves as failures as a result. Surely a mother who has chosen to sacrifice her sleep deserves respect and admiration for her generous mothering.
