We canāt read too much into this, nor can we read too much to the child of any age.
Reading: Of course, the "big gun" is reading to the infant (toddler or child). Nursery Rhymes serve well, at first, and as the infant grows into a toddler, short simple stories and then longer and more complex stories become appropriate.
The activity of reading to an infant (a toddler, or a child) has it all! It provides opportunities to remember many things from the prosody of language, to phonemes, morphemes syntax and vocabulary; and later details about the book itself, from the pictures in the book, to the characters, their names and the story line.
Each time we read to a child, no matter how young or old, it is a mega-shot of growth vitamins in the arm (or more appropriately in the brain) like we wish ginko-baloba would be for us adults.
