Now, Jen and her husband Jake Wall have shared the first moments between Hendrix and his big sister Frankie.
First posting a photo to her Instagram Story, Jen also shared a sweet video that’s sure to become a cherished memory, wheeled out at every birthday and significant moment to come. And occasionally played to remind the kids they actually love each other when they're teenagers.
After giving him a kiss, Frankie appeared to be enamoured with her new little brother in the short clip.
“It’s your baby bro! Say hey Hendrix,” Jake can be heard saying in the video, with Frankie lifting up her hand to wave at him.
It’s no surprise Frankie is already a doting older sister, with the two-year-old tot seen hugging her mum’s baby bump many times over the past nine months.
A few weeks ago, Jen shared a sweet snap with her daughter writing: “Frankie hugging her little bro. Melt!”
And when she announced her pregnancy in July, Jen revealed she couldn’t wait to see her daughter in action as the eldest sibling in the family.
"Round two!!" she wrote. "Jake and I are so happy to share that we are expecting a baby BOY!!! We both feel really blessed and couldn’t be happier to grow our little family! Can’t wait to see our Frankie girl as a big sis!!"
