All of the following individuals are U.S. residents: Kelly (27), her daughter Sydnee (4), and Kelly's mother, June (50). All three lived together until the end of March, when Kelly moved out. Then, in November, Kelly married Austin (29), and Sydnee moved in with Kelly and Austin, who are filing a joint return. Sydnee does not pay over half the cost of her own support. If both households try to claim Sydnee, who is entitled to do so?
