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 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!!!!"
