I Hate Kids (2019)

Nick Pearson is a life-long bachelor who is finally settling down. On the brink of his wedding he is surprised to find he has a 13-year-old son who found him with help from a psychic. The problem is that Nick can't stand kids and would happily send the boy back to live with his biological mother, except that nobody has a clue who that might be. With nowhere to turn, Nick must hit the road with the boy and the neurotic, inept psychic to track down dozens of his ex-flings and ask each the awkward question--with mixed results.
