Reading to children is an invaluable activity. It not only creates lasting memories but also plays a vital role in boosting a child's educational journey. A new study in the *Journal of Developmental and Behavioral Pediatrics* highlights just how important those bedtime stories are for children’s language skills.
Jessica Logan, the study’s lead author, explains that children who are read just one short book daily start kindergarten with 290,000 more words than their peers whose parents don’t read to them. If they hear five books a day, the gap increases to a remarkable 1.4 million words.
Logan refers to this as the “million word gap,” suggesting it helps explain the vast differences in vocabulary and reading proficiency among 5-year-olds. "The word gap of more than 1 million words between children raised in a literacy-rich environment and those who were never read to is striking," said Logan in a statement from The Ohio State University, where she serves as an assistant professor of educational studies. "Children who are exposed to more vocabulary will be better equipped to recognize those words in print when they start school, and they are likely to develop reading skills faster and with less difficulty."
For their research, Logan and her team randomly selected 60 books from a list of popular children's titles. They counted the words in each book and found that, on average, a board book (designed for infants) has 140 words, while a picture book (targeted at toddlers and older children) contains 228 words. With this data, and assuming that board books are replaced by picture books after a child turns three, they were able to estimate the total number of words a child hears from books by the time they reach age 5.
Logan explained that her current research stemmed from a previous study, which revealed that 25 percent of children are never read to, and another 25 percent hear stories only once or twice a week. Research has shown that children's books are particularly effective for teaching vocabulary, as they introduce words that are rarely heard in daily conversation.
This study further underscores the importance of reading, especially in forming healthy reading habits early on. A study from the previous year found that individuals who grow up in homes filled with books—particularly those with over 80 books—tend to have better reading comprehension, and stronger mathematical and digital communication skills.
