Bedtime stories a problem for many parents

From the UK's The Guardian, a sad but true story: bedtime stories a problem for many parents.
My mother-in-law is a professor of literacy and remarked that many children's picture books are actually too "wordy". Picture books and read-aloud need to keep it simple to attract parents as well as kids. I understand the necessity of children hearing as many different words as possible their first year of life, but keeping them simple with beautiful illustrations is the way to keep both parents and children happy.
