"There will be no messing. That's because Maria will be aware that as they step off planes, holding mum's hands, smiling and waving to the crowds, there can't be any crying or terrible twos or tantrums.” A Norland expert Louise Heren told The Sun.
It is believed that the children have a strict 7pm bedtime curfew, which is not to change under any circumstance.
And, in order to prevent fussy eating, new foods and flavours are regularly introduced into the children’s diet.
When it comes to playtime, the children must go outside regardless of the weather!
"Lots of bike rides, playing with their dogs, potentially some gardening. Norland are very into teaching children through play,” adds Louise.
"If it is tipping down, they will still go out. Wet weather is just inappropriate clothing, you have to put the right stuff on."
