What's in a name? For Bristol Palin and her baby daddy Dakota Meyer, it's everything.

The once-warring former couple have been making amends over the course of the past few months, and to show that they are determined to co-parent their 5-month-old daughter, Bristol is willing to give their daughter Dakota's last name.

Court documents, obtained by TMZ, showed that Dakota filed a petition to change Sailor Grace Palin's name to Sailor Grace Palin Meyer. He also said he's now listed on the baby's birth certificate, which wasn't always the case.

Bristol, the daughter of former Vice Presidential candidate Sarah Palin, signed off on the name change.

Certainly, Bristol and Dakota have come a long way from their custody battle that took up a good portion of 2016. But, it seemed that these two were always willing to compromise for the good of Sailor Grace.

In late February, Bristol pleaded with her former fiance to form some semblance of a relationship with their daughter. Text messages between the two were revealed in court documents that showed the two of them having differing views of the situation.

"I want you to be a part of her life, from the bottom of my heart I do," she told Dakota in a late January text message, saying there was nothing holding him back from seeing her.

At the time, Dakota had filed an emergency custody motion asking a judge to rule immediately on a temporary custody agreement.

Bristol opposed the motion saying that his demands would interfere with her consistent breastfeeding. But, a court quickly ruled that Dakota would get to see Sailor every two weeks under the current agreement.

The agreement was the latest in a custody saga, much of which was played out in text messages.

"Please come see her soon," Bristol texted in January. "I know you're busy but I'd even meet you somewhere, she changes so much everyday, I don't want you to miss anything."

Dakota said his schedule would never prevent him from seeing Sailor but he wanted everything worked out.

"There's nothing on my end holding you back Dakota. I want you (and your family) to be in her life as much as possible," she wrote. "It's not about us, and I don't care if you hate me, put it aside and put her first.

"She grows everyday and everyday I literally just think about how much you're missing by not seeing her, so realize I'm not bs'ing you and I want you to be a part of her life, from the bottom of my heart, I do."

Dakota said, "I don't hate you Bristol I have no reason too [sic] but my hands are tied when I legally have no right to a child that is mine."

Showing that the duo has moved on and want what's best for Sailor, Bristol posted a snap to Instagram on Mother's Day showing them with their daughter in Alaska.

"#coparenting," she captioned the image.
