Despite splitting in June, Ben Affleck and Jennifer Garner are consciously coupling up for the holidays.

"Jen and Ben are figuring out right now how they can best spend the holidays together," a source tells People. According to the mag, Jen, "wants to get along with Ben for the kids' sake."

The exes have three children together Violet, Seraphina and Samuel.

Ben has been out of town, filming the movie Live By Night, which he stars in and directs, in Boston. The Oscar winner was back at home in Los Angeles over the weekend and he and his ex came together to take the kids to decorate cupcakes and to the toy store.

"Ben and Jen chatted a bit," says a source. "But mostly they seemed focused on making the day fun for the kids."

We're glad to see the estranged spouses are putting their kids first.
