A blur of feeding and sleeping

An infant tends to lose weight temporarily three to five days after birth. This weight is usually regained after a week. 

Infants during this period do nothing but feed and sleep. They usually do not distinguish between morning and night, and spend most of the day sleeping, 

Neonatal reflexes can be seen during this period where infants move their hands and feet all over the place and also make body movements with no conscious control.

An infant's job is to cry. Answer your baby's cries by taking actions such as feeding or changing their diapers.
