Bristol Palin and Dakota Meyer are co-parenting now

What drama?

Bristol Palin, 25, and her ex-fiancee Dakota Meyer's relationship since welcoming their daughter, Sailor Grace Meyer, has definitely been rocky at best, but the duo seem more committed than ever to making their tiny tot's life stress-free since reaching a custody agreement last month.

One day ahead of Mother's Day, both Bristol and her baby daddy posted an image of them holding onto their 4-month-old baby and captioned it, "#coparenting" and "#coparentingatitsbest."

In the photograph, both parties are smiling and seem extremely happy and the towering mountain in the background seems to have been taken in Bristol's native, Alaska.

In addition to Dakota sharing the same photograph on his Instagram page, he also penned a sweet Mother's Day message to Sarah Palin's oldest daughter.

"Bristol, we definitely haven't always seen eye to eye but one thing that's never been a question is how amazing of a mother you are. And to my mom, thank you. Happy Mother's Day."

Bristol gave birth to Sailor, her second child, on Dec. 23, shortly after she and Dakota, a 27-year-old U.S. Marine vet and 2009 Medal of Honor recipient, called off their engagement.

At the time, Bristol didn't reveal who the father of her child was, but Dakota later tweeted a photo holding his daughter and captioned it, "Best Christmas gift ever." The duo then got into a custody battle, but in March, an Alaska judge ruled that the two would share interim joint legal and physical custody of Sailor. Last week, Dakota filed another petition to have Sailor's name changed from Sailor Grace Palin to Sailor Grace Palin Meyer. A hearing is reportedly set for June on that matter.
