They grow up so fast! Teen Mom 2 star Jenelle Evans just revealed on Twitter that her and her fiancé, David Eason‘s seven-month-old daughter, Ensley, has already started talking.

Jenelle shared the exciting news with her 1.34 million Twitter followers, and it sounds like the engaged couple is in the middle of some ~tough competition~ over what her first real word would be, as she wrote, “Ensley is babbling on and on right now, the race is on.. ‘Momma’ or ‘Dada’ first?!”

The reality star is also the mother of two children which she has from previous relationships, a seven-year-old son, Jace, and a three-year-old son, Kaiser — while David also has two other kids, a son, Kaden, and a daughter, Maryssa. While Jenelle has sparked rumors over the last few weeks that she is pregnant again, both she and David have revealed that they are not having more kids anytime soon.

“I think we’re good. We have a lot of kids together,” she previously told E! News.

Her hubby-to-be added, “We already have so many kids and it’s really time-consuming, it’s hectic. We don’t get that much time for just ourselves.”

We bet all five of these little munchkins can’t wait for Jenelle and David to tie the knot, which they announced they will be doing on Sept. 23, 2017.
