On Friday, Tara took to Instagram to post an adorable photo of herself eating a burger at a cafe while breastfeeding Paddy.
"I’ve always admired mums who have the courage to post unapologetic photos of themselves while nursing their babies as they share the realities of this important part of motherhood," she wrote.
"Breastfeeding or pumping milk, our bodies do amazing things."
Tara said that before becoming a mother, she never understood how breastfeeding in public could be considered "so inappropriate by society".
"And now, as a first time mum, it blew my mind when I heard that 53% of breastfeeding mums don’t feel comfortable breastfeeding in public!' she wrote.
"Today, I share this photo of Paddy and I so that we, along with all of the courageous mums before me, can be a part of the movement that helps to normalise breastfeeding."
Tara, who made the post ahead of World Breastfeeding Week, announced she has partnered with Philips Avent to be part of a campaign that "supports mothers and their breastfeeding journeys".
Tara announced her pregnancy in October last year on Instagram, revealing the baby’s gender and her due date.
The nanny and her husband Nick shared their exciting news in a drone-style video, which showed the parents-to-be sitting on a beach, popping a bottle of champagne alongside the words "baby Shep due May 2021" written in the sand.
"Well, at least one of us was able to enjoy some celebration drinks on our honeymoon...," Tara explained, making light of the fact she was pregnant on their wedding, before revealing the gender of their first child.
The month prior to the pregnancy announcement, Tara and Nick tied the knot at Sol Gardens in the Currumbin Valley, Queensland.
Tara first rose to fame after coming third in Matty J's season of The Bachelor in 2017. The following year, she found love with Sam Cochrane after he proposed to her on Bachelor In Paradise.
The pair never made it to the altar and endured a messy, public split in June 2018.
She then found her happily ever after with long-term friend Nick Shepherdson, who she has known for more than 10 years.
