Can the mean of a discrete variable like the number of children be normally distributed?

Not really. The distribution is not only discrete but also heavily skewed. However, the average number of children in sets of families can be approximated by the normal distribution.

Is a normally distributed variable needed to have a normally distributed sampling distribution.?
Yes, it is.
Is a discrete variable normally described as a word?
No.A discrete variable is a variable that can not assume all possible values within a given range.For example, if I were to conduct a survey on the number of children people had, then my answers would be numbers such as 0, 1, 2 and so forth (i.e. they would be whole numbers). This particular variable could not have a value in between these (a non integer value), such as 1.345, as this makes no sense in this context. This makes the variable discrete.
Is the number of people a discrete variable?
Yes, is a discrete variable.
How to present a variable that is not normally distributed?
There are many variables that are not normally distributed. You can describe them using a probability distribution function or its cumulative version; you can present them graphically.
What does it mean when you say a variable is normally distributed?
It means that the probability distribution function of the variable is the Gaussian or normal distribution.

Can you think of a variable that is normally distributed?
The value of a roll of two dice is normally distributed.
Is number of children a continuous variable or categorical variable?
Neither. It is a discrete variable.
Is height a continuous variable?
Yes. (Although it is normally recorded in a discrete form.)

What is a discrete variable?
A discrete variable is one that cannot take on all values within the limits of the variable.
