Question

Observation and characteristics of an infancy period.​

Answer 1

Explanation:

Infancy is also the period when most of the deciduous, or “baby,” teeth erupt. The front teeth erupt first, usually starting around six months after birth. There are 20 deciduous teeth altogether, and they continue to erupt until about three years of age. Newborns need about 18 hours of sleep each day.
