Safe Infant Sleep: Expert Answers to Your Cosleeping Questions is the first book to foreground the concept of "breastsleeping." Drawing on the historic anthropological relationship between breastfeeding and infant sleep, breastsleeping refers to the phenomenon of breastfeeding mothers bedsharing with their nursing child.
Here are the basics:
With easy access to the breast, babies will night feed without waking their mother, or even fully waking themselves, meaning both mother and child get more sleep.
Bedsharing increases the frequency of night feedings and has been known to extend breastfeeding duration.
Worried about safety? Breastfeeding moms are physiologically attuned to their babies, and are likely to sleep more lightly, rousing if their babies are in danger.
