Jenelle Evans' son Kaiser is 'so happy' since living with his dad, Nathan Griffith, according to family friend Katlyn McCormick. The former Teen Mom 2 star and her husband David Eason, lost custody of her children nearly a month ago and are currently fighting in court to bring their kids back home to them. Everything started when David viciously beat the family dog, Nugget, and eventually shot him, which lead to Jenelle's sons from previous relationships, Kaiser, 4, and Jace, 9, were removed from her care. A few weeks later the troubled couple also her and David's daughter Ensley and David's daughter from a previous relationship, Maryssa.

David's daughter Maryssa,11, is now staying with David's ex-wife Whitney Rich's s mother. According to Katlyn, who remained friends with both Jenelle and Nathan also after their split in 2015, Kaiser is so happy now that he is staying with his dad. The twenty-eight-year-old went on explaining what a great dad Nathan is, and how he has been able to take Kaiser out of his shell and change his whole demeanour to the better.

As reported by Hollywood Life, Katlyn went on saying that Kaiser is well aware of the horrible incident with the family dog and that Nathan has helped him deal with the traumatic experience. According to Katlyn, Kaiser has said himself that he is not scared anymore, which must have been heartbreaking to hear from a four-year-old.

Nathan and his current girlfriend have also taken Kaiser to therapy to help him deal with the trauma, something Kaitlyn says has helped the little boy so much. In his new home environment, Kaiser now has routines and is brought out for fun outings regularly, as opposed to, as Katlyn put it, being "stuck in a house being scared". Clearly siding with Nathan in this custody battle, Katlyn also bashed Jenelle and her actions, saying that the mother of three "could care less", alleging that she is only putting up a fight for the cameras.

As tragic as the situation is, it is great to hear that Kaiser is doing so well since living with his dad, and hopefully, the whole family will be able to put their priorities straight and do what is best for the children.
