Our latest international trip with our toddler was a great success. We had everything planned and organized to keep him entertained throughout both 10 hour-flights! Unfortunately we didn't realize that, as a "new walker", he wouldn't be happy confined for a couple of hours in a stroller at airports, parks, etc. We were so jealous when we saw this couple with a toddler in a cute monkey harness. The kid was happy walking around the crowded Charles De Gaulle airport, while we were chasing our little one.
I've just bought a harness, and after a bit of research I realized that although stuffed animal harnesses are cuter, the backpack version is more useful! Lukas now can carry his own Cheerios.
