We have been traveling to Mexico with our kids all their lives, both of them, now 21 & 16 made their first trip south of the border at 3 months old, or as I said the entire vacation “niña,tres meses” the first time and “niño, tres meses” the second time. We attracted a lot of attention with the babies..all good! (except for maybe as I was boarding the plane)!
1. Get your kids a passport, they will need it to travel to Mexico
2. Put together their own little travel bag with snacks, a favorite toy, blanket, a portable movie player with headphones was always the most valued item, with a few favorite movies.
