"She's ensured there are loads of pictures of him up in their house, so he feels like he has two families, and they do get on well.
"She has instigated a lot of that, rather than Dara. Bea has always been really close to Edo's family, so it's natural that Wolfie should become part of hers. He's a super little boy and extremely cute. It will be interesting to see what happens when they start their own family – but Bea is so caring, his happiness will always be her number one priority."
Wolfie was named after Edo's beloved stepfather Christopher Shale, who died suddenly, aged 56, of a heart attack at the Glastonbury festival in 2011. He and Edo's mother Nikki were great friends of the Duke and Duchess of York and Sarah is godmother to their son Alby, 29.
Beatrice and Edo are expected to set up home in her apartment in St James's Palace.
But property developer Edo specialises in creating lavish, no-expenses spared homes for the super-rich, so the couple may decide to move somewhere bigger.
Dara and Edo both share custody of Wolfie, so for Princess Beatrice, it is a thoroughly modern marriage.
