SIGNING
hahahah! i taught my boys only 1sign - milk. cos tat's e only sign i know. it helps a lot wif my 2nd son cos when he cant speak yet, he'll sign for milk when he's hungry (he was a milk drinker, didnt take solids until 11mths old).
GD/Shichida (right brain)
i doing something similar wif my 3kids now. my kids love flashcards so i do watever i can wif them. i also play memory games, mazes, IQ games (more wif my #1) n also other stuff like painting, coloring, lego, ball games, etc.
i more like "cha-ba-rang" mummy. everything try, everything can. i was even considering montessori prog 4 my elder kids.
