Brian Austin Green has a pragmatic approach to co-parenting with his ex-wife, Megan Fox .

The Beverly Hills, 90210 actor talked about knowing how to pick your battles during a Saturday interview with E! News at Pennsylvanias Steel City Comic Con.

Prioritizing what matters is big for Green, who shares sons Noah, 11, Bodhi, 10, and Journey, 7, with the Transformers star.

The No. 1 is always make sure that everything is centered around the experience of the kids, he explained.

People make a mistake of thinking that theyre gonna do things so the separation doesnt affect the kids, Green went on. Of course, its gonna affect the kids.

He said, The only choice you have is how it affects the kids.

The actor told E! its helpful for him to accept that exes wont exactly see eye-to-eye.
