The Teen Mom 2 cast member -- who will document this exciting time during this season of the aforementioned MTV series -- just welcomed her first daughter Ensley Jolie Eason with beau David Eason. Jace and Kaiser are big brothers to a sister -- better get used to playing with the ladies, guys!
"And she has arrived," the proud mama captioned the family photograph above, shortly after the birth. What a beautiful moment for the trio!
Jenelle and David announced in August that they were expecting a baby girl together, and the 16 and Pregnant alum gushed that they couldn't "be any happier" to meet their brand-new addition. Jenelle made sure to chronicle special moments throughout this pregnancy -- from her boys bonding with their gal sibling (belly kisses are the best!) to a pink-filled shower with her nearest and dearest. And now, the fun with Baby E really begins!
Be sure to offer your congratulations to Jenelle and her family in the comments -- and watch the clan on Teen Mom 2 every Monday to see Jenelle's pregnancy and Ensley's evolution!
