It's amazing for Parents.  

Keep talking to your baby and teach him everything from numbers to letters to science to art. His mind can grasp everything you say. You have till he is seven years old to lay down all the foundation. The brain will absorb all of the. Have fun, mom.

My husband and I just feel sooo blessed by God! We also live in a non-english speaking country. I have 2 kids ( 3 and 1 yr old) and nothing makes us prouder hearing our friends telling us how smart our kids are. i feel so happy listening to my son who's now three speaking in English with alsmost perfect syntax and all..besides being able to communicate using the first language here. At first i was afraid he wouldn't be able to speak or he would get confused because of the language problem, but it actually didn't matter. Right now, he speaks three languages! At home,i still do our routines like reading stories at bedtime even during the day especially on weekends when we're around, talking to them about anything, taking them outside for them to explore things etc. We are enjoying every second with our kids. For you zhizho, just continue talking to your smart son and feeding him everything you know. Good luck!

have a nice day.
