The two kids had some Christmas fun with a nutcracker

Jason Mewes is celebrating an extra special Christmas this year!

On Monday, the Jay and Silent Bob star, 49, celebrated his first Christmas with his baby son Lucien, 10 months. In a photo shared on Instagram, Lucian was seen playing with big sister Logan, 8, who makes the infant laugh as she playfully chomps at him with a nutcracker.

"Lucien’s first Christmas! Logan was an awesome big sister :) Merry Christmas everyone!" Mewes, who shares his kids with wife Jordan Monsanto, wrote.

In November, the proud dad shared a glimpse into his baby son's first Turkey Day — which included some quality Mewes family time in the pool!

To celebrate the holiday, the actor splashed around in the water with his two kids. Alongside the photo of Mewes, his two kiddos and another child in the pool, the actor wrote, "Happy #Thanksgiving!!! 🦃."

In the sweet snapshot, Logan sported a pair of goggles on her head as she gave the camera a side-eye, and baby Lucien flashed a very big, very toothless grin.

In October, Mewes celebrated another holiday milestone — Lucien's first Halloween — by coordinating a costume with both of his kids.

The actor donned a purple suit, green hair spray and a whole lot of makeup as the Joker, and dressed baby Lucien in a matching Joker onesie. Logan dressed up as another DC character, Harley Quinn.

"Let’s put a smile on that face 🤡 Happy #Halloween 🎃 from the Mewes Family ;)," Mewes captioned a photo of the trio.

Mewes welcomed Lucien in February, announcing the news on his Instagram.

The 9-month-old was born on Sunday, Feb. 12, the actor revealed, weighing 6 lbs., 13 oz. and measuring 19½ inches.

"Fast & furious…he almost arrived in the backseat of my car at the hospital entrance," he captioned a set of photos from the day of the newborn's arrival.

"Thank you to our doula @iamhaizehawke, Dr Campbell & the team at Cedars-Sinai for the safe delivery of baby boy. We are home, and Mom & baby are doing great. Our lives are forever changed. Less sleep than last week but worth it 🤍."
