The carpals (wrists) and tarsals (ankles) are not yet ossified in the fetus. The hardening of these bones begins in the first 4 weeks of life outside the womb, and continues for some bones until the age of 12 years.
Children have smaller hearts and blood vessels, higher heart rates, and lower blood pressure compared to adults. Children's cardiovascular systems are still developing and adapting to growth, while adults have fully developed and matured cardiovascular systems.
Babies have distinct physical proportions compared to adults; their heads are relatively larger in proportion to their bodies, making up about 25% of their total length, while an adult's head accounts for about 12-15%. Additionally, infants have shorter legs and a higher body fat percentage, which gives them a rounder appearance. As they grow, their body proportions gradually shift to resemble those of adults, with longer legs and a more balanced head-to-body ratio. This change reflects the different developmental needs and functions during infancy and childhood.

Generally, the size of individual cells does not differ significantly between adults and children; however, the number of cells and overall body size do vary. Adults typically have more cells in total due to their larger body size. Additionally, certain types of cells, like muscle and fat cells, may be larger in adults compared to children because of differences in body composition and development.

Babies have more sensitive hearing than adults. They can hear higher frequencies and softer sounds than adults can. This heightened sensitivity helps babies learn language and communicate with their caregivers.

chocking on infants and children and adults aren't much different but with infants they will cough and might be sick and stop breathing
No. Their brains are not fully developed yet so it would not be fair and right to compare them to adults.
Yeah, unfortunately. But it's not set in stone--everyone has a choice.
Children do not experience bereavement in the same way as adolescents and adults. Preschool children usually do not understand death as final. Some children sometimes begin to act like infants again (wanting bottle feeding, using baby talk, etc.).
