Do your thang, Mila Kunis!
Looks like Jenelle Evans and her boyfriend Nathan Griffith have a lot to be thankful for!
Jenelle posted a few snaps of the newborn to Instagram, and Kaiser looks happy and healthy as he rests on his momma's shoulder and enjoys a visit to an alligator farm with big brother Jace.
Though motherhood hasn't always been easy for Jenelle, we wish her the best of luck with baby Kaiser!
