And Jessie asked for people's prayers for her son as he fights the virus.
She added in a post on Instagram: "Once again I'm in awe of nurses and doctors. It makes me even more proud of my brother, a&e doctor @pondermed and my father, king GP @davidlloyd73 .... please wish baby a speedy recovery."
"He's 9lbs 7 now so he's a stronger and bigger boy than he was when we were last in a hospital room (and the needle went into his hand with louder more powerful screams). Love and best wishes to everyone #nhsheroes #nhs (sic)"
Jessie welcomed her third child into the world in October after an "extreme" birth.
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."
"The midwives (Magda & Daisy) and the doctors and neo natal nurses have been amazing (our first one to welcome us into the ward was named Rosaria and she was extremely comforting)."
