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?

Yung kapatid ng asawa ko, bata pa sya 5 yrs old lang now, english speaking sya ever since. Ngayon na nagsschool na sya nahihirapan sya makipag communicate sa ibang bata kasi di sila magkaintindihan haha. Ok lang po turuan ng english basta maturuan nyo din po ng tagalog at the same time
