The 39-year-old spent Labor Day with his kids and niece.
The 39-year-old took the trio on a boat trip, and he shared a bunch of photos from the experience on Instagram.
Disick captioned the post, "Labor Day weekend was a good 1! Nothing like fam bam."
Penelope, in particular, appeared to have a lot of fun, standing behind her father on the driver's seat as he navigated in one photo, while another showed her smiling and posing for the camera.
Her little brother, Reign, was a little less energized, just chilling in the back of the boat as they drove around.
Though in a later photo, it looks like Reign took a turn helping Disick drive, as did Penelope. Their father even let them adjust the speed.
Meanwhile, North cuddled up to Penelope in a seat in another cute picture.
Many people in the comments loved the family photos, with one person writing, "These are the days the kids will remember! You’re doing a great job Scott!❤️."
Others also praised Disick's parenting, saying, "You're such a fun dad and u can see Penelope adores you."
One fan specifically highlighted how the kids had the correct safety equipment on, although they wished Disick did too, saying, "Love that they all have life jackets… you need one as well."
Many loved how the photos showcased Penelope and North's friendship as well.
Just a week ago, Disick posted a photo of the two girls relaxing and having tea together with the caption "tea time."
Recently, rumors spread that Disick was "excommunicated" from the Kardashian family following ex Kourtney Kardashian's marriage to Travis Barker.
But it turns out that's all they were–rumors–as Kris Jenner cleared it all up.
On the Instagram post for the article from Paper Magazine, Jenner wrote in the comments, "Scott will NEVER be excommunicated from our family….he’s the father of my grandchildren and a special part of our family… we love him and not true! 🥰😍."
