Experts say lack of nutrition in the summer can lead to poor performance once school starts up in the fall.
Multiple Rockford programs are working to make sure that doesn't happen.
School playgrounds across Winnebago and Boone counties have cleared out for summer vacation.
But as Rockford Executive Director of Human Services, George Davis says, the struggle to keep mouths fed and belly's satisfied in our area--does not take a break.
"It affects their ability to be to active and happy and their growth and development," Davis said.
Today marks the kick-off to the summer food program: one of the initiatives to fight childhood hungry in our region.
The federally funded program feeds over 4,000 mouths one meal every day in Boone and Winnebago county.
That's up about 1000 from last year.
But there are still almost 20,000 kids that receive free or reduced lunch that aren't getting fed.
"Children don't have to be participating in a particular program to come to the meal. So, if it's a the boy's club, the girls club or any other organization, that hosts the sites, children can come," Davis said.
Another agency trying to help feed children in the summer is Rock River Valley Pantry.
Every summer they try to collect 10,000 jars of peanut by the end of May, when school lets out.
"Peanut butter is important because it requires no refrigeration and any kid can slap together peanut butter between two pieces of bread," Pantry director Kim Adams-Bakke said.
But at the end of May, they only had half their goal.
They've received some generous donations, but still are in need of more jars.
"When you are providing food for 28-hundred children per month, peanut butter is a staple that we can put in every bag," Adams-Bakke said.
