Teen Mom 2's Kailyn Lowry and Javi Marroquin have been lucky in love for a few years now, and there's no denying that Javi has become a huge part of Kailyn's life. This dude stands by her side in (morning) sickness and in health, and he's had a pretty significant role raising her son, Isaac. Sure, Isaac's still spends plenty of time with his pops, Jo "Nerd In A Cool Kid's Body" Rivera, but Javi's also a father figure in Isaac's life –– so much so that Isaac calls him "daddy."

Javi recently posted an Instagram video of Isaac referring to him as "daddy" (which has already been deleted), and as you might expect, the sweet moment isn't without its controversy. Some fans are shocked that Isaac calls Javi "daddy" especially considering that Jo is very much in the picture.

We're sure Jo is less than thrilled about this development, but what's the big deal? Kailyn's always said that Isaac knows who his father is, and it's clear that he's crazy about Jo. It's perfectly natural that this kiddo would call an important father figure in his life "daddy," and we're sure he has plenty of love to spread around!

Then again, we're not sure that Kail would be thrilled by the prospect of Isaac calling Jo's girlfriend "mommy."

Do you think Isaac should be calling Javi "daddy"? Weigh in below!
