When it comes to babies’ bottoms, the Mattapoisett Congregational Church has them covered, or at least they hope to. The church’s annual bluegrass and folk concert on March 28 will benefit the New Bedford-based Baby Project that provides diapers and formula to families in need.

In July, church members learned that the Baby Project had run out of diapers. They began collecting them through a Sunday school drive.

“It just breaks my heart to think of some poor infant sitting in a dirty diaper for a day and a half because the parents can’t afford another one,” said church member Sue Grosart.

Run by Diane Bolton, the Baby Project began collecting and distributing items five years ago. Each Thursday from noon to 1:30 p.m. parents and guardians can pick up the much-needed items at the St. Anthony of Padua Church Food Pantry in New Bedford.

In December, the congregational church continued its support of the Baby Project with its annual White Gift Service, and members decided to keep the theme going with the spring concert.

Last year, the event raised funds for the church’s mission trip to Appalachia. The concert featured resident rocker David Dunn performing acoustic songs and the New Hampshire-based bluegrass duo Gravel Road, featuring Grosart’s daughter and Mattapoisett native, Beth. (Listen to one of their songs below.) This year, those musicians will return along with Joe Zajak on banjo.

The concert starts at 7 p.m. and tickets are $12 each. “Every penny” will go to the Baby Project, Grosart said. People are also encouraged to bring a pack of diapers to donate. Diapers will also be available to purchase a pack at the event.

As an added incentive, everyone who donates diapers will be entered into a raffle for a gift basket.

Rite Aid and CVS of Fairhaven have agreed to give diapers to the cause as well.

“The more diapers we can get into the hands of these people the better,” said Grosart.

The church had a full house for last year's concert and Grosart is hoping for another good turnout.

“Everybody always seems to have a good time,” she said.

Plus, it’s for a great cause.

“A lot of little baby bottoms will thank you!”
