Harry Potter actor and cartoonist Jessie Cave has welcomed her third child with her partner, comedian Alfie Brown.
Posting to Instagram, she announced the arrival of her baby boy Abraham whilst detailing that he had been taken into the neonatal unit after an "extreme" arrival.
She wrote: "❤️ Abraham “Bam” Benjamin ❤️ Our baby boy was born in the early hours yesterday morning just 40 mins after my waters were broken. Slightly extreme but so were his kicks throughout the pregnancy!
"This has been a very different experience to my first two births... much more humbling, terrifying and out of my control."
"We are currently in the neo natal unit but he’s a strong boy and it’s the safest place for him right now."
Cave thanked the medical staff who had assisted her in her delivery as well as Brown.

She went on to describe the moment her son was wheeled away to the neonatal unit shortly after being born as "one of the hardest moments of my life" and sent "love and respect" to mothers who had experienced the same.
The couple are already parents to son Donnie, six, and daughter Margot, four.
Cave has previously spoken about the unconventional start to their relationship after she found she was pregnant with their first child after a one night stand.
The 33-year-old starred as Lavender Brown in the Harry Potter film series, appearing in Half-Blood Prince and Deathly Hallows Part 1 and 2.
She's also had roles in TV series Trollied, Black Mirror and Call the Midwife.
Cave currently hosts podcast We Can't Talk About That Right Now with her younger sister Bebe, also an actor.
Brown is the son of composer Steve Brown and actor and impressionist Jan Ravens, known for her parts on Dead Ringers and Spitting Image.
