She is preparing to welcome her fourth child with her husband Bobby Kootstra.

And Katherine Ryan showed off her growing baby bump as she packed her hospital bag ahead of her baby's arrival in a video posted to Instagram on Friday.

The comedian, 42, displayed her blossoming stomach in a black bra and blue leggings as she filmed herself in the mirror, with the text 'What's in my hospital bag,' placed on top.

She then opened her suitcase and explained each item, saying: 'People have asked about my hospital bag. I don't stay long, I don't need much. 

'I got personalised onesies from Etsy for a boy and a girl, embroidered with the names that we like, but who knows.

'We got a backup with a White Company set from Jamie Laing and Sophie. Violet's (her daughter) going home one for luck.

'I got a swaddle bag, nappies, breast pads, Hevea dummy, Frida cooling pads, Frida wipes, nappies.

'Boy shorts, labour and delivery gown robe, Skims pyjamas for when I'm showered, and toiletries.'

She continued: 'Just like a face cleanser, body wash, wet shampoo and conditioner, Spritz for Bits, nipple cream - I don't know if I'll need it though, but there it is.

'Showing Joonbyrd body cream, she said: 'Got these off of Cult Beauty and one of them said Violet on it.

'Some toner, Caudalie is just such a luxurious treat, toothpaste, and some cra*** deodorant because it's sulphate-free.

'Cosmetic Consult face and body wipes, and some little treats for my eyes (shows eye drops).

'And a quilted robe.'

Alongside the post, she penned: 'What’s in my hospital bag? (tbh not much).'

Katherine and her husband Bobby have been together since 2018, but have known each other since they were children as they grew up together in Canada. 

Childhood sweethearts, the two parted ways initially before rekindling their romance this side of the Atlantic.

The couple previously revealed in a series of the family's reality show that they 'wanted the option of having a fourth [child].' 

The series saw the couple exploring their marriage through therapy before visiting a fertility clinic.

Katherine admitted in the scenes which aired in February that she knew conceiving a fourth child would be challenging thanks to both her and Bobby's age.

'It's not that surprising that over 40 women have fewer follicles than we once did,' said Katherine. 'But we talk a lot about male fertility as well, which is on a steep decline. But I would still like a fourth baby.

'We are so blessed to have the kids that we do have. Having children is not for everyone, but I personally really like making people. I think it's a superpower if you can do it.'

She explained at the time how she and her husband had never previously struggled with getting pregnant but had suffered multiple losses.

'We've always gotten pregnant with the babies quite quickly. I've been pregnant five times in five years, but that also means I've had three miscarriages in five years and the likelihood of that increases as you get older,' she explained.

Speaking to OK! last year, she also ruled out surrogacy, explaining: 'I think surrogacy is wonderful. It's beautiful for people who are really eager to offer it and for couples who need it but for me, I think it would be exploitative.' 

Appearing on the Chris Moyles Show in November, she admitted: 'I'd have so many more if I could.

'If I was a dad, I'd be like Robert De Niro having them. Because you can have kids when you're 80 as a dad. You just have to.'
