In a second snapshot from the party, this one in black-and-white, Alastair stood between his parents as they hugged and looked at the camera.
Penny later added a similar image to her Instagram grid, which showed the trio smiling, clearly having the time of their lives.
The special constable captioned the picture: "Our boy's birthday celebrations were made so special by the love and laughter of family and friends."
The couple are doting parents
The statuesque blonde shares two sons with Rod, who she married in 2007: Alastair and his younger brother Aiden, who is ten.
Penny is a doting mum and explained one aspect of her approach to raising young children in a heartfelt Instagram post last year, after sparking debate on Loose Women by revealing that she was a fan of the 'cry it out' technique.
The mum-of-two detailed how she and Rod used the technique under the supervision of their paediatrician, which involved weaning Alastair off his night-time feeds and letting him cry himself to sleep "over 2/3 nights" before, as Penny explained, "he slept the whole night through!!!!"
