You can be reading a book, newspaper, magazine, electronic device, or files on a computer. You can be checking a train schedule, sports scores, or stock prices. You can be following a recipe or trying to decipher instructions for assembling a piece of furniture.
Whenever your preschooler sees you reading--anything--make it into a big deal. Point it out. Show her that you are reading for a purpose--to learn something, to get something done, or just because you love it.
You are your child's first teacher. Show her that reading is a skill you engage in, and find useful and pleasurable. Model being a reader. Don't be shy about it. Get caught reading!
