The 37-year-old shared a sweet snap of baby Willow Wendy Wood as she lay wrapped in a pink blanket and donning a cute knitted beanie.
"🌸💕I could honestly stare at you all day little Miss Willow Wendy Wood," the proud new mum wrote.
"We knew before you were born we would love you but honestly words cannot do it justice," she continued.
And Markoski isn't the only doting family member! Her fiancée Sam Wood and her daughter Eve also marked the exciting occasion with adorable Instagram posts.
Wood, 36, also shared some sweet words for Markoski and his stepdaughter Eve.
"Mumma you were amazing and I love you more than ever. Eve, you look so natural holding your little sister."
Emotional stuff aside, the former Bachelor completed his caption with a joke, "Dad- stop crying 😭🙈." Too cute!
