The reality gave birth to her second child, son Kaiser, with boyfriend Nathan Griffith on 30 June, and shared a sweet family photo to Twitter earlier today.
Alongside the picture of herself, Nathan, Kaiser and her son Jace, four, she wrote: "I'm so blessed to have my little family. I love them so much and I'm so happy how far I've come within these past two years."
How precious is little Kaiser?!
And how grown up is Jace getting?! We watched Jenelle adapting to becoming a mother to Jace on Teen Mom and the highs and lows of her life as she raised him.
Now, she's a mum again and clearly loving every minute.
Another ridiculously cute picture shows herself cuddling little Kaiser, who is giving a peace sign while snuggled into her neck. Aww!
How sweet is he?!
Jenelle is currently on screens in the US alongside Nathan on Teen Mom 2. As well as filming the MTV show, she's been hard at work at college, studying to become a surgical assistant.
