The first thing you have to do if you want to bring your child(ren) on your trip is to ask your host about it. Many hosts do not accept minors, particularly locations such as hostels.
Hosts at hostels generally don’t host minors, especially children, because the environment isn’t a good fit for them. However, other hosts such as NGOs, farms, or smaller lodging options like bed and breakfasts can host them because it’s a very different environment where they can also participate. It’s extremely important to ask your host before your trip, because there’s a good chance they won’t be able to host your child(ren).
Another important thing to remember is that children can’t have a Worldpackers profile because they are underage and WP relocation and insurance rights only apply to the adult traveler with a confirmed trip through the platform. Additionally, the host has to consider that in this situation, they’ll be hosting another person who also needs a place to sleep. And as the purpose of Worldpackers is the collaborative exchange skills for accommodation, this makes it more difficult to host children.
