Interesting take on things in the article, however..
We are late life parents, my daughter is my only child and arrived when I was 47. 11 years on and it's like a second childhood for me and my wife. Maybe being older we look at things differently to younger parents who always seem to be on a timetable to do everything at warp speed, mostly due to not thinking things through or planning ahead.
After 9 years of a MH, we changed to a caravan. Our daughter has also been fortunate to have flown long haul a lot from the US to New Zealand, Australia, Singapore and Malaysia. In the MH to Poland and around europe.
We have always spent time explaining to our daughter months in advance of long trips, where we are going, what we will likely do and see. Having Merlin Annual Passes are a benefit (available at a sensible price on offer in January) as there are so many places you can visit whilst on a caravan trip. The beauty is it doesn't matter if you arrive late and leave early on a full weekend or week or two as you are not paying a daily entry fee. One of our favourite CL's is near Alton Towers.
We play 'yellow car' on journeys to sites. Spot tower cranes, trains etc.
Days out be it hiking to a beach, through woods etc make for energy sapping fun.
Meal times in the caravan are a family effort.
Board games, colouring books including adult ones are fun for all the family.
Taking a friend of our daughter on weekend trips gives new insights too, and company for our daughter of her own age. Caravan sites are great places for kids to enhance social skills and make new friends. Plus lots of fresh air and exercise. Wonderful life education for them.
