For John and Amy Cervantes, birthdays have always been a big deal — a welcome excuse to celebrate life. When their eldest son, Alex, turned three, in 2005, they invited 20 friends to a nearby park and hired a clown to paint faces and make balloon animals.

Not long after that, the couple were brainstorming ways to teach Alex about giving to others. “That’ s when a spark went off,” says Amy. “We wanted to do something that would have a strong effect on our community, that wasn’t already being  done, and that our young children could participate in. I started wondering what less fortunate kids do on their birthdays. The next day, we called a local shelter.” What they learned is that homeless children typically don’t do anything to celebrate. No cake. No gifts. No party.

Several weeks later, the family threw a party at the shelter for the children who had birthdays that month. They decorated, served cake, and led 50 kids in the uncertain situation. Alex helped fill and pass out goody bags and presents. Since that first party, the couple have turned their simple idea into Birthday Blessings, a nonprofit that hosts monthly parties at ten shelters in and around Charlotte, North Carolina. The group also delivers baby supplies to new moms in the shelters. And it considerately sends treats to elementary schools so homeless kids can celebrate their birthdays with friends.

To date, Birthday Blessings has thrown more than 500 parties and handed out over 22,000 favors to nearly 4,000 homeless children. The idea is spreading fast, with additional chapters set to start in Atlanta, Cincinnati, and northeast Indiana. Birthday Blessings is operated entirely by volunteers with Amy, a stay-at-home mom, in charge. John attempts his career as an investment adviser while setting up the group’s similar network and running its capital campaign. The charity will take almost anything — toys, baby items — as long as it’s not used. “These kids never get anything new,” John says. “It makes a big difference to them psychologically.”

Being part of this“labor of love,” as Amy puts it, is already making an impression on the boys. When Alex turned seven, his grandparents sent a birthday check. “The first thing he said when he opened it,” Amy recalls, “was that he wanted to give half to the birthday kids.”
