Picture books are bigger than board books, with (be careful!) rippable pages and, usually, a slightly longer, more developed story. You can introduce picture books into the story time mix right from the newborn days, but the sweet spot for picture books is later toddlerhood and beyond. Your child’s awareness of the world is always expanding, and picture books tell more ambitious stories, going to new places, and helping the child to understand and navigate each stage of life (a new sibling, the beginning of preschool, conflict with a friend, fear of the dark, picky eating, and so on).
Answer Egg yolk color is really just an indicator of the hen’s diet. If they eat more yellow-orange carotenoids, or natural pigments, it affects and changes the yolk’s color. Orange yolks have the same amount of protein and fat than lighter yolks but studies have shown that eggs from pasture-raised hens have more omega-3s and vitamins but less cholesterol due to healthier more natural feed. Orange yolks are an indication of a well balanced and highly nutritous diet and many people claim they taste better as well. Eggs from hens that have access to grasses and insects as part of their diet tend to have orange colored yokes that are firmer and egg shells that are thicker.
No one will pay you anyway. Novelist Neil Gaiman says people come up to every author with the same offer (which he always politely rejects): “They’ll tell you the Idea (the hard bit), you write it down and turn it into a novel (the easy bit), the two of you can split the money fifty-fifty.” Business ideas are similarly unsellable. As investor Tim Berry says , “The way real people with real ideas get value from them is by building a company to implement those ideas.” Unless the Patent Office will let you register it, it’s worthless. So don’t hand your idea to an expert like you’re whispering into a college grad’s ear, “One word: Plastics.” Just get it out there, and if the experts want it, they’ll find it.
