Traveling with a baby: about my trip to Machu Picchu with my 4-month-old

I recently traveled to Machu Picchu with a few friends and my son, who was four months old at the time. Everyone thought I was crazy for taking him. I am not sure what they were afraid of… malaria? Too high. Water-borne illness? Breastfeeding. Ear pain on the flight? Exaggerated. Consistent nap time? Overrated. It was during this time that I realized that children are extremely adaptable. It is adults who are not.
