In preparation for our annual family trip to Mexico, my children and I have been talking about what we will do, who we will see, and where Mexico is located. In trying to raise children that have a global awareness, my husband and I always have a globe or map handy to point out different countries, the languages they speak, and any fact we happen to know about that country. Our daughter is mesmorized by maps and loves to see the route that our plane will travel when we go on vacation with Abuelita. We have been pulling out old pictures from albums to help my younger son familiarize himself with the place we are going and the things we will do. Although our trip to Mexico is most definitely a vacation and a rest for us, we love to intergrate ourselves with the culture, hang out with local families, play with local children, frequent neighborhood restaurants, and connect with the community. With all of the Spanish practice we do at home and all of the 'horas de espanol', traveling to Mexico helps my children make a connection to their heritage and communicate with children their own age, and have fun learning more Spanish! I am also looking forward to a few evenings of babysitting from Abuelita! :)
I have found this site, Travel for Kids: Mexico to be a great asset for tips and recommendation for traveling with children.
A great book that we like that highlights many of the traditional Mexican customes and tourist spots is Off We Go to Mexico! By Laurie Krebs, Christopher Corr
