The tot is set to join his royal parents when they embark on a 10-day tour of southern Africa on September 23. Archie took his first flight this summer to Ibiza where the family celebrated the Duchess of Sussex’s 38th birthday before flying to Nice a week later for a short stay at singer Elton John’s villa.
But the baby’s upcoming private jet journey to the Rainbow Nation’s port city will be nearly six times longer than the flights he has taken in the past.
Baby sleep expert and reflux specialist Alison Scott-Wright said Harry, 35, and his wife should be prepared for the possibility of their baby bloating.
Cabin pressure and the high altitude can pose challenges to even the most frequent flyers and babies and young children are no exception.
She told Express.co.uk: “If you have a water bottle on a plane it blows out and there is the same affect on our digestive system.

“You cannot prevent that, it happens to all of us.
“There’s nothing you can do so it might be a bit tricky.
“For a couple of days there might be spit-ups or vomits.”
As well as bloating passengers can also experience cramping and irregular digestion after a 12-hour flight.

Ms Scott-Wright, author of The Sensational Baby Sleep Plan, is known as the “Magic Sleep Fairy” to her readers.
