Recent Study by Therese Doan, Annelise Gardiner, Caryl Gay and Kathreen Lee reveals that breastfeeding brings more night sleep for parents. In their paper published in the Journal of Perinatal and Neonatal Nursing they explain that parents of infants who were breastfed slept an average 40 minutes more than parents of formula fed babies.
After reading the report of this study in the Mothering Magazine I did a simple pool among my friends and we agreed that in general breastfed babies do eat more often during the night than formula fed babies, but breastfeeding mothers (who are also co-sleeping) do not need to fully awake for nursing. I just pull a shirt and roll on the side...and fall back asleep while the little one has his snack or is calming down after a bad dream.
And every new mother knows how precious are those 40 minutes :-)
