sunsweet, when my daughter is 2, i bought her the peter and jane book and read to her, the 1A and 1B, surprisingly she started with this book and able to read the book after a while. so i thought she memorizing the words or pages, one day my hubby skip pages, but she can read the words, he was impressed.
there is 2 school of reading, the phonics way or the sight reading way. in most school, they learn phonics. but when u read to them often, they pick up the sight reading way. i only know all these when my daughter went for assessment for a k2 english class, and i realized she is so so in phonics, but better in sight reading. so mommies out there, no harm reading to ur kids, make it a habit to tell bedtime stories, for me, my rule is 2 year old 2 stories, 3 year old 3 stories, if not it's never ending hahahahaha.
