Well,

From the grammatical point of view the word child is neutral (neither male nor female) which means you would have to use the personal pronoun it and the possessive adjective its. However, I prefer referring to a child as they so as to make sure the child can be a girl as well as a boy. Even better if you use the plural form children: Let's take a look at how children learn their mother tongue.
