Model Danielle, 27, called an ambulance to the home she shares with footballer boyfriend Jamie in the Midlands when five-month-old Harry - who was born 10 weeks prematurely - had trouble breathing.
A spokesperson for the couple said: "Harry was taken to hospital this afternoon after suffering breathing problems at home.
"Danielle was alone with Harry and Archie, as Jamie was at football training. She called an ambulance and Harry was taken straight to hospital where he is undergoing tests and will stay in to be under observation over night."
And former Celebrity Big Brother housemate Danielle shared her fears with her followers on Twitter as she waited in the hospital with Harry.
She tweeted: "My poor little baby back in hospital never been so frightened in all my life my kids are my life."
Harry had to spend five weeks in a neonatal unit after his premature birth, being allowed home to join mum, dad and brother Archie (pictured above) in August.
Harry has been bulking up well and his mum recently posted a picture on Twitter showing that he was now 8lbs - double his birth weight.
