OMG, you guys. Jenelle Evans’s adorable little boy turns four today! We can hardly believe that we watched Jace come into the world on 16 and Pregnant four years ago when his mama was just a high schooler.

Jace’s mama started getting us all excited for the festivities yesterday, when she posted an adorable pic of mom and son on her Instagram, and dished to fans about some of the big birthday plans. Although Jenelle’s son still currently lives with his grandma, Barbara Evans, rest assured that Jenelle has a ton of personal surprises in store for his big day.

For his official birthday, Jace will be spending all day with his mama, just the two of them. Jenelle shared with fans on August 1 that she has a very “special day” with her son planned. Perhaps they will hit up a water park to test out Jace’s new swimming skills (he’s been taking mommy and me lessons), or maybe they’ll visit some wild animals (the jungle safari Kailyn Lowry took last week is located in Jenelle’s new home town of Myrtle Beach). Whatever they do to celebrate, we’re sure Jace will just be happy to spend time with his mommy. These two will have a blast!

According to Jenelle, Jace’s big fourth birthday celebration will last well into the weekend. “Birthday party on Saturday,” the proud mom tweeted on August. We’re sure that she spent the whole day running around getting balloons, cake, and maybe even a piñata.

Have the best time celebrating with your little buddies, Jace!
