The model was in Europe on holiday when she gave birth to her fourth child, but as little Jett is still having difficulty breathing, the family has remained abroad while he is hospital.
Writing in her The Sun column today, Katie said: "I'm still abroad as Jett has now developed breathing problems. No idea when we are back. I flew our mums out to visit us this week. No matter how old you are, you always need your mum near when the chips are down."
She added on Twitter: "It's soooo nice to have our mums over xxxx."
Katie gave birth to Jett early, after she was taken to hospital while on holiday with Kieran.
The author was told her amniotic sac had torn, leaving her unborn child vulnerable to inflection. Jett was born several weeks early via Caesearean section and weighed 5lbs 2oz.
This week, Katie admitted to fans she was feeling homesick after weeks abroad, saying: "Me & [Kieran] miss home soo much & miss our family & friends its been 5 weeks now! Jett still in baby unit with breathing problems :((."
Kieran, meanwhile, wrote: "Its been a tough 3 weeks but we are closer and more in love than ever before. I love my wife @MissKatiePrice."
Katie and Kieran married in January in The Bahamas following a whirlwind romance and Christmas proposal, announcing their pregnancy soon afterwards.
Jett is the first child for them, while Katie also has three children from previous relationships: 11-year-old Harvey, Junior, eight, and six-year-old Princess.
