Is Princess Diana never having met James Hewitt until Prince Harry was two years old a good excuse?

No this is a bad excuse, and these people are liars. Anyone that actually believes what they say is an idiot.

Prince Harry is a ringer for the young prince Philip.

This is a rubbish theory around them. We all know that Harry is Charles" son, she has met James after Harry"s birth when he was already a toddler and I have seen a lot of documentaries and interviews that Diana gave

It is a fact about time this nonsense about Hewitt and Harry stopped.

we all Know that Charles is Harrys father PERIOD

It’s proof

She was seeing Hewitt long before Harry was born. They had a love nest in Exminster, Devon and were seen there on many occasions. Ask the people who live there.

Royal lies.

Well I've just moved your question back from Egypt. They have rubbish theory and just want to censor, it's akin to the cult of personality around Kim Jong Un.

It is a fact that Diana and Hewitt began their affair around the time Harry was two years old. Before then, Diana still harbored hopes that she and Charles would work through their difficulties and make their marriage work. One way Diana sought to please Charles was to give him his children.

Diana and Charles, along with their two sons, had gone on vacation to Spain, to stay with the Spanish royals, and it was during this time that it became apparent the marriage just wasn't going to work out. Charles had been talking to Camilla, and restarted their affair by then. Diana decided to embark on her own affair. Hewitt was her sons' riding instructor. She found him attractive, struck up a friendship that turned into an affair.

Royals are under surveillance by their protection officers. Diana's officer would accompany Diana to some of her visits to the Hewitt household in the country.
