My son doesn't want to drink water. His already 3 years old. What should I do.

umiinom po ba sya ng milk and fruit juices? you can also give him fresh buko juice for now. if he likes fruit juices, you can try putting bits of fruits sa water para magkaroon ng lasa. example, cucumber water, strawberry water, etc. otherwise, consult your pedia po kung ano pa magandang gawin.
