The Angels hitmaker's partner Ayda Field gave birth to Theodora 'Teddy' Rose on 18 September, but Williams reveals her arrival into the world was far from smooth.
He tells The Sun: "I cut the cord but, bless her, I cut it while she was still inside Ayda. Teddy was going blue because the umbilical cord was caught around her neck.
"I had to be quick with the scissors. It was like the first 30 minutes of Saving Private Ryan down there. It was like Ayda vs Predator. She'd say the same thing. It's an image that won't go away."
The pop star also revealed he took in gas and air intended for this wife as she went through labour, adding: "I had loads of it... Every time Ayda had a contraction I thought, 'I can have gas and air too.' I've got such huge respect for women who have babies."
Williams reveals his first-born is now suffering from acid reflux, but insists he wouldn't swap parenthood for anything: "I enjoy changing nappies and I really like being a daddy. I don't want to be anything other than a daddy and a husband. Life's pretty perfect right now."
