Klum asked her father to film the births of all four of her children, as she wanted to capture every moment.
She explained to The Times magazine: “I want to have a film for my kids. If they don’t want to see it, we can throw it away... I wanted Seal by my side, not filming.
"And I don’t want to hire someone I don’t know. Like, ‘Hey, can you film this?’ I had no problem with my dad doing it at all.
"I’m his kid. He made me! So he can watch my kids being born. To me that is totally normal.”

Klum has three children - Henry, nine, Johan, eight, and Lou, five, - with her former long-term partner, Seal and one daughter, Helene or 'Leni', 10, from a previous relationship who Seal later adopted in 2009.
So thanks to her dad, she can now experience the whole birthing process again for each of her children.
