After only a year of marriage, Leah Messer and Corey Simms split up. There were plenty of rumors about why, but it came down to cheating. Messer wasn't ready to settle down and be married, so she stepped out on Simms. This complicated things for co-parenting. While they have been able to work things out, for the most part, Messer attempting to get Simms to accept what Aliannah's needs are has been a struggle. Getting a power chair for their daughter to use was a huge hang up for the dad. Leah fought hard for her little girl, and eventually, the chair was bought and used.

Update

Since Messer has been filming “Teen Mom 2,” there isn't much time where viewers remember the little girl not having glasses. This is a hard thing for Leah to hear. She is very supportive of her daughter, but her heart breaks when things like this come up. Now that Ali is getting older, the differences between her and Aleeah are more noticeable. More questions are being asked, and Messer has to find the answers in a compassionate way for her little girl.
