In the USA we generally refer to a child as being a "toddler" between the ages of 18 months and 3 years of age. However, my 5-year-old "preschooler" enjoys many of the activities in this book as well as his almost 2-year-old sister. I have learned that the best "gift" a parent can give a child is his/her undivided attention for a period of time. I have personally found that by spending one-on-one time with each of my children, even if only for 5-10 minutes one or two times a day, there is a positive change in the daily demeanor and degree of cooperation I get. They look forward to it. It's not that I can't think of things to do with my children, but on one of those really difficult days (I'm sure you know what I mean), it's a big help to glance quickly at some creative simple ideas to choose from. Also, this book comes in handy when a play-date becomes boring or unfriendly. When I am able to redirect the unhappy kids to the kitchen table for a "mommy supervised activity" from this book, the enthusiastic smiles almost always instantly return. When my daughter was born, and big brother's jealousy was on the rise, I used many ideas in this book for the much appreciated one-on-one time... "mommy/big brother time" -- without baby sister. Along with "The Toddler Busy Book", I also recommend another helpful little book filled with positive discipline suggestions for parents of 2-5 year-olds called "The Pocket Parent." I like the easy reference A-Z format of this trouble-shooting guide that addresses many of the most annoying behaviors that too often challenge my sanity. These two books have brought more peace to our family, more cooperation from our children, and more ways for us to enjoy one another.
