And, wanting to share her baby boy's achievement with the world, the 25-year-old took to Twitter to let all her fans know she now has a walker on her hands.
Frankie tweeted: "My little man is now walking... In a crab like manor... But still!!! Where's my baby gone?! Proud mummy!"
Aww how cute!
Shortly after sending her tweet, Frankie posted a funny Instagram snap proving that you can be a mum yourself, but that still doesn't stop your own mother from carrying out her parenting duties...
Including pointing out spelling mistakes once in a while.
Sharing a screenshot of a text conversation between herself and her mum, Frankie showed her followers a message her mum had sent her.
It read: "Whoops! Just seen your tweet about P. Manor should be spelt manner!!!!!"
Captioning her photo, the Saturdays singer said: "Oops sorry Mum! She has eyes everywhere! Can't get away with anything! Ha."
Although she may have been unlucky with her typo, Frankie had a little more luck catching Parker - who recently turned one years old - walking.
All weekend, Frankie and her husband Wayne Bridge have been in Blackpool as the mum-of-one competed in this week's live show of Strictly Come Dancing from the Blackpool Tower Ballroom.
But, making it home just in time, it seems Frankie didn't miss out on little Parker's memorable moment - and even managed to bag one of her own with her latest Strictly performance.
Performing the Quickstep with her dance partner Kevin Clifton, Frankie scored two 10s on the night. One from head judge Len Goodman - his first of the series - and another from Bruno Tonioli.
