The image, she said, was actually captured by her younger sister Casey Patridge Loza.
"@caseyloza always capturing me in moments," Audrina captioned the pic of the mommy-daughter moment, adding the hashtag "mom on the go."
The photo was actually taken last week, with Casey using the hashtags "casual breakfast #she makes breastfeeding look cool."
The photo shows Audrina wearing a Jack Daniels t-shirt with ripped off sleeves. She looks off in the distance while holding her baby girl in her lap.
"As a new mother, I'm learning a lot of new things along the way. I am by no means an expert at caring for a baby, but I was pleasantly surprised by the amount of maternal instincts I had when Kirra arrived! But, instincts can only take you so far," she wrote earlier this month. "Corey and I were lucky enough to have friends and family who were willing to help us out with baby-related questions."
Two months after Kirra was born, Audrina finally shared images of her daughter.
"We are so incredibly lucky! Kirra is the happiest, most beautiful baby with a constant smile and lots of goo-ing and gaa-ing!" Audrian wrote on August 24. "She loves giving Corey and I the biggest smiles, but I can't wait until she giggles the first time — right now she gives lot of expressions but no noise. She sleeps 6-7 hours a night (only waking up once or twice) and is pretty laid-back (unless of course she's hungry, has to burp, needs a diaper change or gets restless!)."
She continued, "I absolutely love being a mom — Kirra is my number one priority. If I'm being completely honest, the first month of no sleep, C-Section recovery, unpacking, and getting back into the swing of things was pretty grueling. But, at the end of the day, all I had to do was take one look at Kirra and none of that mattered anymore."
