i also noticed that... my son started his school at the age of 2, it's bec. he's jealous with his cousins who go to school but not him. he started to speak straight sentences when he was a year and half. by that time he can count and recite the alphabet too.
by the age of 3 they are having proper lessons and when he's 4 he can write and read.
when we went here though he can't speak proper english, i knew he'll catch up with other kids bec. he's bright. to my surprised they don't do proper lessons yet here with that age.
now he speaks english better than me and don't speak tagalog na
well, i'm glad that he studied in PI first before we came here. all his teachers are amazed bec. he can write and read already. i always get good comments how bright he is, from other parents too
