Dear Dorer,
Firstly, pardon me for being direct...
To see "results", u must 1st take that fast result idea out of your head. A child input years can be till 3 yrs old if u start from birth. Some show output only from 4 yrs old onwards. When that mindset of seeing results, u might never see them at all. Cos your expectation is always there and u will never see even if your child do show anything.
I started off with these brain training methods with my boy and always feel pressured to see results since he started at age 2 which is really kind of late for such training methods. Partly also becos I paid high fees for those classes like Shichida. I realized that that was very wrong after finding out abt GD. I had to totally change my mindset and teach at a pace we both enjoyed and we had great fun together.
Now i would tell my frens to teach with just simply love for the child and use the sessions as great bonding time rather than drilling time. Me and my boy would call our sessions "fun time" cos that's when he gets to spend more than 1 hr with my full attention and games and cards that i made just for him. I am a working mummy, hence time is very precious to me.. I was doing the program all by myself with no help at all from hubby then, hence making regular sessions a challenge. But effort spent these years are worth it for sure. I am now enjoying my "results" with a child independent in his studies and also in other areas like sports. Btw, he dun even read till he is 4+..and he was a slow reader then..He is now in 1st grade but he is reading at 4th grader level. I am surprised but yet very happy cos I have not expected anything from him and there he is showing me the results of our happy sessions.
By the way, no need to rush for that 30 mths thingy. We started dot cards at age 2 with dots and he did not have any issues with learning maths at all. What u need is just consistency in showing those cards for the next few months cos child after 3 might have difficulty seeing the dots. Remember to do at a pace which is comfortable for both of u. No point getting pressured cos child can sense your stress immediately without u showing it on your face. That hinders child's learning mood and ability.
Just carry on with your language cards as per schedule. Dun worry abt whether is he "learning" them yet. Dun test..never even attempt to do it especially when child is unwilling to even play the game.
Some kids just talks later..once they start, they never stop...maybe u will find that "annoying" later

. My nephew a mth younger than my boy starts talking in full sentences only when is was almost 4. He can sure annoy everyone at anytime right now.

U can speak as many languages as u like with child. Reading can be keep to maybe a max of 2 languages?
Just want to share my thought...
