What Do You Know About Babies?

Explanation
A baby who is only a day old is referred to as a newborn because this term specifically denotes a baby who has just been born and is in the earliest stage of life. The term "newborn" is commonly used to describe infants in their first few weeks of life, highlighting their fragility and vulnerability. It is a distinct stage in a baby's development before they progress into being a youngster or a kid.

Explanation
Colic is a condition that affects babies and is characterized by excessive crying, typically occurring in the evening or at night. Babies with colic often cry for long periods of time and are difficult to soothe. It is a common condition in infants and can cause distress for both the baby and the parents.

Explanation
Babies between one and three years of age are called toddlers because this stage of development is characterized by their ability to start walking independently, hence the term "toddler" which refers to their unsteady and wobbly steps. During this period, children also begin to explore their surroundings, develop language skills, and show increased independence in their actions and decision-making. The term "foetus" refers to the stage of development before birth, "crawlers" refers to babies who are in the stage of crawling, and "biters" does not accurately describe the age group mentioned in the question.

Explanation
Babies are not able to speak as they have not yet developed the necessary language skills and vocal abilities. While they can breathe, see, and smile, speaking requires the coordination of various muscles in the mouth, throat, and vocal cords, as well as the ability to understand and produce language. Therefore, speaking is the one ability that babies do not possess.

Explanation
The correct answer is stillborn. This term refers to babies who do not survive the birthing process and are born without any signs of life. It specifically applies to babies who are born after 20 weeks of gestation. The term "unborn" refers to babies who are still in the womb and have not been born yet. "Kids" typically refers to older children and is not applicable in this context.

Explanation
The correct answer is "girl" because it is the term used to refer to a female baby. "Lady" and "woman" are more appropriate for adult females, while "youngster" is a general term that can be used for both males and females.

Explanation
The correct answer is "boy" because a male baby refers to a human child who is male. The term "boy" is commonly used to describe a male child, typically from infancy to adolescence. As the child grows older, he may eventually become a teenager and then a man. However, at the stage of being a baby, the appropriate term to use is "boy."

Explanation
The correct answer is "to walk unsteadily". This means that toddling refers to the act of walking in an unsteady or wobbly manner, often seen in young children who are just learning to walk. It implies a lack of balance or stability while moving on foot.

Explanation
Babies have ten fingers, as they are born with five fingers on each hand.

Explanation
A newborn does not have any teeth. Teeth usually start to emerge between 6 to 12 months of age, so at the time of birth, a newborn does not have any teeth.
