My (British-born) son first went to the Phils for 4 months when he was 3 months old.
Second 'trip' was from 14 months old to almost 4 years old (including a few months in Hong Kong)....then he started pre-school here in the UK.
Next 'trip' was from 8 years old to 11 years old.
Didn't do him any harm, but make sure you find a good school in the Phils.
Kids are very adaptable and thrive on new experiences, and as an ex-forces kid moving between countries, and new schools every year....I know.
