Posting a black and white shot of herself tenderly holding the newborn, Katie wrote: 'so in love with my little runner bean she is tiny perfect and my miracle.'
In the snap, Katie has kept her child's face out of shot, though the beginnings of hair can be seen on the top of the tot's head.
Price welcomed her fifth child two and a half weeks ago, and says she and husband Kieran Hayler now feel their family is complete.
The couple also have one-year-old Jett together, while Katie has three children from previous relationships.
In May, Katie Price was shocked to discover Kieran had been cheating on her with two of her close friends, Jane Pountney and Chrissy Thomas.
Outing him on twitter, she announced they would be divorcing and began criticising her former pal, Jane, for her betrayal.
It certainly seems things are back on track for the pair however, with Kieran apparently being overcome with emotion at his daughter's birth.
