Throughout the first year of life, your baby will grow at a tremendously fast
rate. In fact, by the end of the first year they will have tripled
in birth
weight, length is usually doubled,and by their first birthday,
most infants will be crawling and even may be taking a timid first
step!
The most essential ingredient in infant care is a warm, responsive,
and dependable adult caregiver. Try to spend lots of time holding,
cuddling,
and playing with the infants in your care. You will be richly
rewarded with babbles, smiles, and squeals of laughter.
