The model and former Miss Wales, 31, shared her woes with the world when she tweeted that herself and Ariana were suffering with a sickness bug and stuck on the sofa at home.
Sharing a bare-faced selfie of herself and her baby girl, Imogen wrote: "Poorly baby and poorly mammy #sickness #bug #bothofus."
While Imogen still managed to look pretty in the snap despite feeling "horrid", little Ariana is cute-as-a-button and fast asleep in her mum's arms.
Worried mum Imogen later asked her Twitter followers: "Ariana hasn't been sick all day and now won't sleep without her milk. Shall I give?! I don't want it to make her sick again?!"
Hours later, after a good night's sleep, Imogen returned to Twitter to rejoice in the fact that Ariana was finally bug-free.
She tweeted: "Ahhhhh what a difference 24hrs makes! Ariana is smiley and herself again yay!!!!!"
Just as well Imogen and her family are going on holiday tomorrow (3 February) - sounds like just the tonic after a few days under the weather.
Ariana, her first child with Australian boyfriend Adam Horsley, turns one this month.
