Isaac was born in 2010, and his father is Jo Rivera, Kailyn’s high school boyfriend. Much of Kailyn’s storyline on “Teen Mom 2” has revolved around her co-parenting relationship with Jo.

The show has depicted their struggles and progress, from their breakup and custody disputes to their attempts to work together for Isaac’s well-being. Over the years, both Kailyn and Jo have moved on to new relationships and expanded their families, but they continue to navigate co-parenting Isaac together.

Kailyn & Jo share 50/50 custody for their son Isaac that now goes by the name Elliot.

How did Jo react?

Kailyn Lowry wasn’t the first person Isaac opened up to about his sexuality, but it wasn’t clearly stated who the person in question was.

It could have been his father, Jo Rivera.

According to Isaac’s mom Kailyn, his father Jo had a positive reaction to the news, ‘he was really proud’, she revealed.
