Audrey Roloff shares photo of little daughter Ember next to her cousin, Jackson

Zack and Tori Roloff's baby boy Jackson celebrated his first birthday last weekend, and his 8-month-old niece Ember posed with him for an adorable photo.

Ember's proud mother, Audrey Roloff, shared the photo with her 760,000 Instagram followers. They loved it too because the snapshot received 72,000 in less than two days!

Audrey wrote in the caption that Ember, unfortunately, couldn't stay awake until the end of Jackson's birthday celebrations, but she was grateful that they have one photo of the babies.

The first image in the slide is of Audrey and Jeremy holding baby Jackson. They wished him a happy birthday and said they will always love him.

'I think this is the first picture of us with Jackson since he was born! All the pictures become OF the babies instead of WITH the babies.'

Her followers rushed to the comment section of the photo to share their thoughts. Cecilia Martínez-Santos loved how Ember gripped Jackson's toe and how 'her face is full of sunscreen.'

Heather Evans remarked that 'they are the sweetest lil cousins,' while Lynn Lloyd said the adorable image is 'frame worthy.' She also used the hashtag 'so precious.'

Anna Espino added that Ember is going to adore her cousin and that she'll be his protector, while Debbie Williams said it is wonderful that the cousin will grow up to share memories on their grandparents' farm.

On Jackson's first birthday, mother Tori shared the last monthly update with her fans, even though it breaks her heart that her son is growing up so fast.

She said Jackson's personality 'has really taken shape this month and by golly he is hilarious.' Clapping is his new favorite activity, and he smiles from ear-to-ear when his family members join in.

The 1-year-old is fond of his father, Zach, and loves being the center of attention. If Zach doesn't pay attention to him, Jackson will yell to get his father's attention.
