So my spouse and I have since day 0 (that is, when the fetus was still in the womb) spoken all our languages - Tagalog, French, Taiwanese Holo-oe, the Taiwanese variety of Mandarin, and American English - to our child, who is now a bit younger than 2 years old (the child has also learned some Chamorro in school and will hopefully learn my heritage language Siraya when older). As a linguist, I know for a scientific fact that this person's mental universe is gonna be - well, likely already is - rich, diverse, and wonderful. Here's just me trying to "visualize" my baby's multilingual world by quoting some favorite words and phrases :)
