Matthew McCann has gone through a lot of changes since the first season of Teen Mom 3 was filmed. Not only has he finally sobered up (high five, friend!), he's grown a chin strap (we take that high five back…), got himself a fiancée, and become candle salesman.

Ch-ch-ch-ch-changes!

But perhaps the biggest transition of all in Matt's life is that he's finally stepping up to the plate and doing his best to be a good father to his daughter, Arabella.

Matt hadn't been in Arabella's life for a year, but he recently filed for visitation rights and now he gets to see his little lady every Wednesday and every other Saturday. Not half bad considering that it was just a few weeks ago that Bellie barely knew who her daddy was!

So far, it seems like visitation has been going super well for Matt, and he took it to Twitter to share photos of his most recent hang sesh with Arabella. "Daddy daughter time, I love you, Arabella," Matt posted to Twitter along with a slew of completely adorable photos of himself and Bellie.

Sigh, nothing like a father-daughter selfie session!

We're thrilled that Matt has finally realized how important it is for him to be in Arabella's life, and hopefully his new interest in parenting will continue. Of course, Matt's baby mama, Teen Mom 3's Alexandria Sekella, is less than thrilled about the fact that her wayward ex has wandered back into the picture (who can blame her?), but hopefully she and Matt will be able to successfully co-parent their kiddo.
