Whitney Wilson, a 39-year-old therapist, watches her three children play at a park in the Kansas City suburb of Prairie Village, Kansas, on Friday, June 14, 2024. On Father's Day, she and her wife, Jen Wilson, will pack up their 9-year-old son, 7-year-old daughter and 3-year-old son and take them to visit the sperm donor who made it all possible: David Titterington. To the kids, this-godfather-like figure is alternatively called "bio dad," "donor dad" or "blood father." (AP Photo/Heather Hollingsworth)
