sometime in childhood

Explanation:

During childhood, learning of a second language is easier. Children begin to understand a second language in 3 to 7 months after exposure to this language. In two years, they can begin to communicate fluent in the second language. Second language is easily learnt by children than adults due to the fact that the window of opportunity for language learning and mastery is still much open to them.
