When does baby sleep through the night without you?

Train from birth: There are hundreds of babies that die each year from co-sleeping with parents. Either smothered or strangled in bed linen.These are avoidable deaths. Babies should be put in a crib alone from birth & helped settle from a distance. Feeding on awakening rather than tired allows them to learn to settle without your body contact. No baby sleeps more than 4hr without waking but can resettle if allowed.
