Babies are born with innate reflexes to
________ prime them to survive and thrive.

A(n) newborns head is about
________ one- quarter the total body length; and the proportion continues to change into adulthood.
The average newborn weighs approximately
7.5 pounds (5.8lb - 8.13lb) at full-term
The head is significantly larger taking up
50 percent of body weight when developing in utero, and 25 percent of body weight in infancy
Shaken baby syndrome
brain swelling and hemorrhaging
Examples of infant reflexes
Rooting Sucking Moro Grasping
In the first few days, newborns typically
lose weight as they adjust to life outside of the womb and get used to feeding; however, this is followed by a rapid period of growth.
Body proportions of infancy are also not
evenly distributed
Younger babies need
support for head, tummy time to increase head control and support
The average 2-year-old weighs
26 to 32 pounds
Growth rate is considerably slower in
the second year.
By the time an infant is ~4 months old,
they usually double in weight
By one year an infant’s weight
has tripled
By 2 yrs old, the weight is
4x their original birth weight.
Head should be
protected
The baby should never be
shaken
Shaken baby syndrome
brain swelling and hemorrhaging
As individuals develop from infancy through adulthood, one of the most noticeable physical changes is
that the head becomes smaller in relation to the rest of the body.
At 2 months
the head is about half the total body length
At 5 months
the head is about a third of the total body length
