Heidi Klum & Seal Co-Parent on Aspen Mountain

Heidi Klum and Seal have the co-parenting thing down pat -- just take your kids on a luxurious ski vacation ... works every time.

The exes reunited with their 4 children in Aspen. It's an annual holiday trip for Klum and the kids, but Seal hasn't usually attended since their big D.

Seems like Seal and Heidi are totally on the same page now. Except for the whole skiing vs. snowboarding thing.
