Over more than six decades, tens of thousands of mothers, fathers, grandparents, guardians, and other caretakers have reached out to Globe Santa for help at Christmas.

And since 1956, Globe Santa, a program of the Boston Globe Foundation, has been there to lend a hand.

With four weeks to go for this season, Santa’s mail bin is filling up with requests from families who are struggling to make ends meet and still provide presents for their children on Christmas Day.

A single mother from a city west of Boston wrote to Globe Santa on behalf of her three boys, ages 12, 3, and soon to be 2. Her two youngest boys have been diagnosed with autism, their mother wrote, and she was forced to leave her job to provide full-time care.

Oftentimes, she said in her letter, it seems like an endless stream of therapeutic services that are both exhausting and expensive. “They receive a combined total of 45 hours per week in . . . services,’’ she wrote.

The boys’ mother went on to say that her 12-year-old has sacrificed to help her care for his younger brothers, but the family has little money for anything other than the bare essentials.

“Christmas is bittersweet this year,’’ she wrote. “While I’d love to give them all the world, I know I just won’t be able to.’’

Thanks to Globe Santa, instead of worrying about how to keep her sons from feeling left out, she and the boys will be able to spend Christmas morning opening presents as a family.

Last year alone, 34,325 children in 19,182 Eastern Massachusetts families woke up to the joy of finding presents under their trees courtesy of Globe Santa. But none of these memorable mornings would have be possible without the generosity of all those who support Globe Santa, many of whom make giving to the campaign part of their annual tradition.
