Bristol Palin’s family appears to have fallen head over heels for her baby daughter Sailor Grace – and nobody more so than her seven-year-old brother Trig.
In a sweet snapshot shared on her Instagram account on Monday afternoon, the 25-year-old revealed just how smitten her younger brother, who has Down syndrome, is with his niece, as he cradled the three-and-a-half-week-old infant in his lap, while his sister protectively placed her arm around his shoulders.
‘Trig officially loves her,’ Bristol captioned the shot, which appears to have been taken in her home in Alaska, and sees the close-knit trio perched on a white sofa along with her dog.

Happy families: Bristol Palin expressed her joy over the loving bond that her brother Trig, who has Down syndrome, has formed with her newborn daughter Sailor Grace, with this sweet Instagram image
Proud mommy: The 25-year-old shared this image of her daughter on Instagram last week
The mother-of-two added the hashtag #mybrotherhasmodechromosomesthanyou, referencing the additional chromosome all Down syndrome sufferers are born with.
This is the second time in a matter of days that Bristol has shared an image of her beloved brother on Instagram; just last week, the Alaskan posted a snap of her son Tripp, who is also seven, posed with Trig and her elder brother Track, 26.
‘Three of my favorites,’ she captioned the image, which sees her older brother with his arms wrapped around Tripp and Trig.
Since the birth of her baby, which was announced on Christmas Eve, Bristol has happily shared numerous images of Sailor Grace on her social media accounts, including one cute portrait posted on her account just last week, which saw the little girl sucking on a pink pacifier while wrapped in a cozy white blanket.
Bristol opted to post the picture without a caption, instead using an emoticon of a heart to show her love for her daughter.
In the photo, Sailor can be seen in her hot pink carrier as she looks up at her mommy, who is presumably taking her picture.

Close-knit: Bristol often shares images of Trig on social media, including this image of the two of them posing together which she posted back in December, not long before she gave birth to her daughter
Quality time: The mom-of-two, who is clearly over the moon with her little girl, shared this snapshot of herself cuddling with Sailor earlier this month
Bristol, who often shares photos of her children and family adventures on Instagram, announced her daughter’s birth on social media with a photo of her cuddling her newborn in bed.
‘My sweet Sailor Grace was born yesterday, our family couldn’t be more complete,’ she wrote.
Meanwhile, Medal of Honor recipient Dakota Meyer, 27, shared his own precious snap of the mother with her newborn on his Twitter account on Christmas Eve, after months of speculation over whether he is in fact Sailor’s father.
Although Bristol has never personally confirmed who fathered the newborn, she had strongly suggested that Dakota is the child’s dad, writing on her personal blog in June that she had believed she was ‘heading towards’ a ‘bigger family’ and ‘more kids’ during her relationship with Dakota, adding that this feeling had caused her to ‘get ahead of herself’ and get pregnant.
However, Dakota is now being forced to take a paternity test as part of the former couple’s increasingly bitter custody battle over her new baby.
Court documents seen by Daily Mail Online reveal that Meyer’s bid for joint custody in a suit filed in Kentucky and Alaska has stalled pending the results of the paternity test. A question has also been raised over the actual birth date of Bristol’s baby.
Great holiday: Bristol announced that she had given birth to her second child on December 23, sharing the news on Christmas Eve
Doting dad: Dakota Meyer confirmed that he is the father of Bristol’s baby with this touching Twitter picture, however, some believe the baby was actually born on November 4 because of the date scribbled on her IV line
The Instagram photo posted by Bristol announcing the birth of Sailor on December 24, places the birth date one day earlier. The date of birth on court papers filed in the custody case is also given as December 23.
But the same Instagram picture posted by Dakota with the caption ‘Best Christmas present ever!!’ reveals a detail whited out in Palin’s account – the date scribbled on her IV line.
There, in black and white, is a date that appears to read November 4 – placing the birth almost two months before Palin claimed.
Meanwhile, the mother-of-two hasn’t wasted any time hiding out at home after the birth of her daughter.
Earlier this month, she left her two-week-old newborn at home to hit up the shooting range with her mother, former Republican vice presidential candidate Sarah Palin, and her sister Willow, 21
The reality star shared a photo of herself aiming a semi-automatic rifle, as well as a short video that sees her shooting a handgun at a target, during a firearms training class with Mat-Su Tactical.

Special bond: Bristol posted this snap of her seven-year-old son Tripp smiling down at his sister shortly after the baby girl was born
Bristol also posted a picture of herself with her mom and sister posed alongside a group of other family members and friends, captioning the snapshot ‘target practice’ along with a video of her practicing her shot.
In the short clip, which Bristol captioned ‘bullseye’, she can be seen pointing a handgun at a piece of wood featuring four orange and green targets.
Just one day after the outing, Bristol shared a photo of herself cuddling Sailor. And despite her previous statements about being married before having another child, she appears to be over the moon with her baby girl.
After her son Tripp was born, Bristol claimed publicly that she’d never have premarital sex again. She partnered with the Candie’s Foundation to promote abstinence.
She told Good Morning America: ‘I’m not going to have sex until I’m married. I can guarantee it.’
Bristol gave birth to her son with high school boyfriend Levi Johnston in 2008 while her mother, Sarah, was campaigning as Senator John McCain’s running mate in the presidential election.
