Tim's hack made me recall my own painful detangling sessions when I was a preschooler. My parents must have spent at least $100 on bottles of detangling spray — this would have been so much more effective.
At about age two, detangling our daughter's hair after a bath became a struggle of screaming and crying. We invented a game to "get the kangaroos out of her hair," but it didn't help much.
Alas, combing the hair out while the conditioner/detangler was still in her hair has been the best solution we can find. Now it's *almost* a painless experience.
