Prince William, 37, has to travel for long trips overseas as part of his role in the Royal Family.
This is to avoid being away from them for too long, something Kate Middleton no doubt agrees with.
During one royal tour, however, he revealed a downside to this.
The four royals travelled to Canada in 2016 for eight days, with three-year-old George and Charlotte who was just 17 months old.
With a long flight to the country, it also means jet lag was most likely to be experienced.
Prince William previously said: “The jet lag has been a bit interesting since we got back,” when talking about how the children were adjusting.
However, he also added they were on their “best behaviour” and it was “nice to take the children with us”.
Jet lag can be difficult to get over with symptoms of extreme tiredness when the body is trying to adjust to the new time zone.
Their next royal tour, yet to be announced, may include their newest family member Prince Louis who is seven months old.
Prince Harry and Meghan Markle recently conducted their first royal tour as a married couple.
The pair spoke about their jet lag in the country, with Meghan particularly struggling due to being pregnant.
She said how being pregnant was similar to jet lag, feeling tired. Meghan was forced to pull out of a few activities to rest.
However, she credited yoga for helping her relax and sleep during the trip.
Other Royal Family members have their own way of tackling the tricky travel problem.
Prince Harry was spotted wearing an Oura ring, which is used to travel fitness and sleep patterns.
This can help travellers adjust to sleeping in the correct time zone easier and avoid jet lag
The Queen has been known to use homoeopathic medicines and barley sugar to alleviate the symptoms.
Experts often advise against sugar as it can make symptoms worse, however.
