No, SNOO comforts fussing when a baby is tired but does not settle the cries of real hunger or discomfort. Be sure to wake and feed your infant per your doctor’s recommendations, until she has regained her birth weight.
Breastmilk is the best source of nutrition for babies. It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
