Chelsea Houska's baby boy, Watson Cole DeBoer, is getting bigger by the day.

Although fans will have to wait another couple of months before they officially meet Watson on Teen Mom 2, the longtime reality star and her husband, Cole DeBoer, treat fans to new photos of their son on their Twitter and Instagram accounts.

"This bub loves being outside," Houska wrote in the caption of her latest photo on Instagram, which featured her four-month-old son wearing a blue baseball cap and yellow shirt.

Along with his latest photo of Watson, Houska's husband, Cole, announced that their son had reached his four-month birthday last month.

"[Four] months old already!!! I couldn't be more proud and blessed," he wrote in the caption of the photo.

Houska and DeBoer welcomed Watson, this past January, after announcing the Teen Mom 2 star's pregnancy to fans in July of last year.

At the time the reality star announced she was pregnant with her second child, she and DeBoer were just months away from tying the knot, although, some believed they would postpone the wedding.

However, Houska didn't want to wait to marry DeBoer and proceeded with her plans to wed in October of last year.

Houska is also mom to her daughter, Aubree, whose father, Adam Lind, is often seen on episodes of Teen Mom 2.

To see more of Chelsea Houska and her family, including her husband, Cole DeBoer, don't miss the upcoming premiere of Teen Mom 2 season eight, which is expected to air this summer on MTV.
