I was thinking of teaching my child English as his first language, do you think that would be okay, or would he have issues stuyding Filipino later on?

Malaki kasi ang magiging impact ng first language sa socialization ng anak mo later on. Safest ang tagalog as first lamguage pero isabay ang english. Ang utak naman ng bata ay parang sponge. They could learn at least 4 languages hanggat di pa sila nag sisix years old I think and this has something to do woth theor brain development
