Just began traveling in Belize with my 9-month-old, Shanti (and wife and mother-in-law support crew). Anyway, read about all the guerilla diaper-changing and more on my blog, beginning with this post from Gales Point:

The best part about traveling with an infant in Belize? Free babysitting at every restaurant! Two nights in a row, the waitress brought our food, then automatically reached for Shanti, who disappeared inside the restaurant to shower everyone with smiles and giggles. Outside, Tay, Louise, and I ate and listened with pride to the sweet sound of Shanti-inspired Belizean belly laughter.

Belize with little ones is great! So kid friendly! Have fun
