Well done to you and your family. Your children are blessed to be shown that life breathes adventure.
We, too have taken a less than conventional lifestyle. Ours started in 2007 with a motorhome bought sight-unseen in the UK. We travelled Europe with our enormous Great Dane for a year living on a 'tenner' a day (plus dog food). We sold it a year later for 200 quid less and a new clutch.
Now we, like you, do housesits/pet sits, (same site.) Mostly in Canada or the Orient, occasionally France and Spain.
We could fill our entire year if we wanted but are now a little picky. Many of our clients are repeats. As we are also talented renovators we tend to do some long sits 4-6 months.
Keep the wind in your sails and may they blow where you wish. Stay healthy.
Keep writing and detailing your journey there are millions who would love to hear your words.
