How long does caffeine stay in breastmilk?

Oh my God... Please tell me you are not doing Cocaine and breastfeeding. Please, if you don't want to be a mother, if partying is too important for you than place that child for adoption, its as easy as making a phone call. Don't ruin that little baby's life like you're ruining yours. That baby didn't ask to be born but she/he does need someone competent and able to take of her/him. Please do the right thing for the baby and either get help or allow the baby a chance to find a family that want to love it and care for it, not a mother who does coke while breastfeeding!
