The neonatal period (birth to 1 month) is a time of extensive and ongoing system transition from uterine environment to external world, this includes the initial period after birth which is referred to as the perinatal period. Your baby will spend his or her early days and weeks in different states: deep sleep, light sleep, drowsy, quiet alert, active alert, crying. While newborns sleep about 16 hours out of every day, their sleep patterns are unpredictable; they may sleep for a few minutes or a few hours at a time. Normal infant fussiness starts at about 1-3 weeks, peaks at about 6-8 weeks and is gone by about 3-4 months. Most babies will “fuss” about 2-4 hours per day, no matter what you do. They want to be “in arms” or at the breast very frequently and fuss even though you attempt to calm them. Most of the time, the congestion and runny nose is uncomfortable for your little one but isn't serious. But call the doctor if your baby is so stuffed up she has trouble feeding or sleeping, if she seems especially cranky, or if nasal symptoms last longer than 10-14 days. Vomiting
