Teen Mom 2's Jenelle Evans gave birth to her second son back in June and this week the MTV star's little Kaiser turned four months old.

Evans announced the four-month mark on Twitter a little late, though she did spend the day with her son, the first child together for her and boyfriend Nathan Griffith.

Even if Evans' announcement did seem as somewhat of an afterthought, the reality star doted on Kaiser Thursday morning, snapping a few photos before bringing Kaiser to visit his grandmother.

Evans and Griffith get a lot of heat from critics when it comes to parenting, especially since they don't have custody of their older children from previous relationships. Griffith had a thing or two to say about the allegations of abuse, neglect, and overall unfit parenting when he posted a statement on Twitter Thursday.

Right now Evans' mother Barbara has custody of her five-year-old son Jace, but the MTV star is looking to bring her son home sometime within the next year.
