^sis just let her play around with playdough, Legos, or making art crafts (paggamit ng scissors,etc), coloring, drawing doodles..
On topic: What i did was read to my then-toddlers every night, or anytime during the day pag may time. We have lots of books. Storybooks, children's books, children's encyclopedias (maraming pictures para interesting), and more storybooks. Minsan sila lang tumitingin tingin sa mga pages. Hanggang eventually sila na pinagbabasa ko sa gabi.
With reading ang dami ng kasama dyan -- identifying objects, spelling, colors, new words, etc.
Now they're school-aged kids, mahilig sila magbasa ng books.
With numbers, it's better to teach them while doing something or relating it to everyday activities (counting cookies, pagnabawasan kinain na cookies edi subtraction yun, etc)
I'm one of those moms who believe na habang bata pa, toddler/preschool, what they need more is play (outside at the playground, or inside the house with toys). That's how they learn. By incorporating lessons through play. And with play, they will also learn how to interact well with others. Being kind with playmates, saying please/thank you/sorry/excuse me, sharing toys and taking turns, etc. sa tingin ko mas importante to learn at that age.
