Teaching babies stem

Learning starts from home. I believe the one who's always with them is responsible for whatever they've learned. Instead of forcing them to study, observe first what catches their interests. And you can use those interests to teach them. I didn't teach my 5-yr old daughter who've learned counting and alphabet just by watching CDs of nursery rhymes. I just encourage her and guide her. And correct her whenever I've heard something wrong. Now she know addition and subtraction, can spell number words, and can read fast.
