tonker - a typical child, and teenager, can learn to communicate in 3 months.
After 6 month, they will speak fluently, and master language after 1 year.
Including the local accent...! They probably will teach you at home...

When I settled in Buenos Aires, at 49 of age, I did quite good after 3 months.
Asking my way around, ordering in restaurants, conversations in pubs with locals.
Of course, I "immersed" myself with the language.
Newspapers, television, tango song lyrics, Asterix cartoon books for kids.
And a little dictionary in my pocket... ¡Momentito Che! - ¿Puedo mirar aca?
Then I met my wife, she was my best teacher. Included all dirty words.
She spoke no English whatsoever, except YES and NO...
After 1 year, I could insult every cab driver in Lunfardo, the city's dialect.
15 years gone by, I sometimes forget English, and think in Castellano.
Your kids will appreciate the opportunity, even if it will be hard the first weeks.
