What is the main source of energy to a newborn first few days after birth?

The main source of energy for a newborn in the first few days after birth is glucose.

Here's why:

* Stored Glycogen: Newborns are born with a store of glycogen (a form of stored glucose) in their liver. This glycogen provides energy in the first few days.

* Breastmilk/Formula: While newborns should be encouraged to breastfeed or receive formula as soon as possible, their digestive system takes a few days to fully develop the enzymes needed to efficiently digest and absorb fat from milk.

* Fat: Although breastmilk and formula are rich in fat, newborns initially get more energy from glucose in the early days.

Important Note: It's crucial for newborns to receive adequate nutrition through breastmilk or formula. While the glycogen stores provide initial energy, they are depleted quickly.
