Why did you chose English as your child's primary language? Aren't they struggling at school with the Filipino subjects? How about with conversing with non-English speaking classmates or friends?

What we do for our daughter (we started since her birth) is to talk to her in both languages, these are Tagalog and English. To avoid confusion, my husband talks to her in Tagalog while I do it in English. It worked for us. While she converses more fluently and comfortably in English, she can still understand some Tagalog words. The reason we did this is because our daughter's cousins are all based in English-speaking countries. She's able to communicate with them very well. I let her play with non-English speaking playmates so her Tagalog is also developed. I'm homeschooling her so I can see where she struggles and helps her to cope and overcome.
