Our son Malcolm was a few months short of two years when we started planning for our move to the USA.
We decided to start talking to him mainly in English to help him prepare for the transition since he will be surrounded by English-speaking Americans.
Nope, that is not how it turned out. We were wrong.
Teach Filipino first!
Looking back, the same reasoning would have helped our son acquire Filipino as a mother-tongue first. Since he’s surrounded by English-speaking people–in church, at school, and in our neighborhood he could easily pick the language up.
