Mary's Parents Are Giving Her a Party to Celebrate Her

Mary's parents are giving her a party to celebrate her 5th birthday. Mary's brother Mike, who will be at the party along with Mary's friends, turned 3 two months ago. Aunt Marion, a therapy patient of yours, was invited to the party and is in a quandary about whether or not she should bring any gifts and, if so, just for Mary, or for Mike, too. With the party just a week away, she brings up the matter during her therapy session. What would you do if you were her and why?

A) Not feel obligated to bring anything. Just seeing their aunt will be present enough for both kids.
B) Bring a gift for Mary only since the party is for her. Besides, it is not a good idea to spoil a 3-year-old with too many gifts, especially since it is not even his birthday.
C) Bring a birthday gift for Mary and a small token gift for Mike.
D) Bring gifts of equal cost for both kids since Aunt Marion loves them both equally.
