Katie, 35, gave birth to Jett in August while in Europe on holiday and has recently returned home to the UK with him and hubby Kieran Hayler.
Last night (18 September), the mum-of-four snuggled her little man down in his frilly white crib before taking a photograph and sharing it with fans on Twitter.
All that can be seen in the snap is a little bundle wrapped in a cable knit blanket, as his head is hidden underneath the cot's hood.
Alongside the picture, Katie commented: "Baby Jett fast asleep while me and hubby @kieran0322 are watching tv in bed, eating chocolate and drinking a cuppa tea."
She has also tweeted a photograph of one of Jett's babygros, which says: "50% Kieran, 50% Katie, 100% Jett."
It's been a tough time for Katie lately, so she definitely deserved an early night with her man.
The star, who has three other children - Harvey, Junior and Princess - from previous relationships, was on a road trip break with Kieran last month when she was rushed into hospital with pregnancy complications.
Once Jett was born, they were forced to stay abroad until their son was strong enough to make the journey home to England.
Meanwhile, Katie has also been faced with the upset of saucy sex snaps of herself being stolen.
Yesterday (18 September), she confirmed that someone had been arrested and charged in connection with alleged incident.
She also insisted she wasn't "worried" about the intimate snaps, which allegedly went missing from her home, adding: "It's NOT affecting my relationship."
