I want to start reading to my child. Any rules? How long should I start reading to her? She is 6 months old. Is it too early to start reading?

nono. its nv too early to read to ur little ones. we started reading to my 11mth boy when he was jus 3mths haha although he dun understand but he could see the differ pictures in the book and he enjoyed it. now he would wan to take a book and see the picture by himself. try the hungry caterpillar book or the eric carle books its really quite a nice read especially THE GIVING TREE.
