Coloring books generally have a theme of sorts. It might be that they are based on a Disney movie, or it is about animals, or vehicles, or something else. When selecting books for your children, remember that they will want to express their creativity, and will have a lot of fun with any coloring book, but will be more interested in a coloring booklet with a theme that appeals to them. Choose a color book that features their favorite characters, or the item of interest in their life. For example, if your little boy just loves trains, get a Thomas the Train coloring book. If your little girl is as girly as they come, look for the Disney Princess coloring book, or possibly Strawberry Shortcake.
Often at times, the trip starts at the airport with excited and maybe nervous children preparing for what may be their first time on an airplane. Thankfully, most airlines will allow pre-boarding for families with young children to avoid the crush of the regular boarding call. Arriving at the airport in plenty of time to familiarize your children with the airport processes will help and will allow also allow them some time to explore the airport. Regardless of if you are traveling by air or by car, always remember to pack snacks, drinks, books and other attention holders to avoid the dreaded, "Im bored" complaints. An extra change of clothes also helps in the event of any travel related illnesses.
One great family bonding that I can suggest for a family who has a small child with them is coloring books. The majority of the children love to paint and color pictures that are create to serve with that purpose. As parents, you can give them a hand in accomplishing this task. Why not give them a portion of your valuable time so that you wont give them reason to be revolted with you for acting the part of being their parents? I, myself adore coloring books. I can envision how my mother and I will try to color pages. She would teach me how to color pictures and what hue should I apply to a certain part of the image. Green for the leaves and red for the petals.... I can still remember the exact picture that we always trace and color.
