Putting their daughter first! Rob Kardashian and Blac Chyna, who share 2-year-old daughter Dream, want what’s best for their baby — whatever that takes.

“They are on speaking terms, and they are working hard to have a better relationship to coparent Dream,” a source tells Us Weekly.

The exes split in December 2016, one month after welcoming their baby girl.

“Angela and I are both actively co-parenting and there are no pending or active custody cases,” the Arthur George sock creator, 31, wrote on Twitter on February 26, using Chyna’s real name, Angela White.

She replied to his tweet with, “Robert and I only concern is what’s in the best interest of our daughter that we both equally love. Additionally, Robert is a wonderful father to our Dreamy!”

The messages came two weeks after the Lashed by Blac Chyna creator, 30, who shares 6-year-old son King Cairo with her ex Tyga, called out Kardashian and the rapper, 29, in an Instagram Live.

“Ya know what’s so wild to me is that I never asked Tyga for child support, Rob for child support or whatever and then we just went to court, or whatnot, and I tried to squash it, which I did,” she said at the time. “But none of that comes out. It’s only negative s–t with Chyna, Angela White.”

The businesswoman added: “We went to court mediation and s–t and I squashed it ‘cause I never wanted no money from Rob, ‘cause it was never about that, period. I have kids by two guys that f–king tricked me, whatever, and they don’t give me s–t, no child support and I’m sick of that s–t. Rob didn’t help me, Tyga ain’t help me, Toni ain’t help me, but like try to like, smack me down, period, and I’m just letting y’all know this, all this s–t, I built BY MYSELF.”
