Emma Hector, 30, from Bolton, was breastfeeding baby Naomi Rose in bed when she fell asleep. Her husband Allen, 42, found their baby's lifeless body with his wife, her breast covering the baby's face. The little girl had blood in her mouth.
Emma - who has two other daughters - said she drank the wine at around 6pm before she fed Naomi. She said she had not eaten all day because she was nervous about a forthcoming social services appointment.
She told reporters: "It is awful what has happened and I am not proud of my behaviour. No mother should be drinking at all.
"Since that day I have not taken one drop of alcohol. I should have been 100% sober and that is what I have to live with. I believe I have failed completely because I am her mum."
The tragic mum was initially arrested on suspicion of 'overlay' – suffocating a child while asleep, but when pathologists could not prove Naomi Rose died as a result of her actions, the charges were dropped.
Frantic attempts were made to resuscitate Naomi Rose by the family's neighour Sheila Bentley, and also by staff at the Royal Bolton Hospital, but she was unable to be revived.
Coroner Jennifer Leeming recorded a narrative verdict.
