A Missouri mom with an oversupply of breast milk donated her liquid gold to help families affected by Hurricane Harvey.

Danielle Palmer, who lives near St. Louis, shared a photo on Facebook of a cooler overflowing with bottles of breast milk over the weekend, saying she donated 1,040 ounces to help mothers of babies in Texas.

Palmer's son Truett, who was born in late February, is unable to nurse, because of a congenital heart defect. So, she has been pumping every day since he was born. Palmer stockpiled the supply she donated in the two months she spent in the hospital with him.

"I have two other boys," Palmer told USA TODAY. "I’ve always had an oversupply. When I first had Truett, I was pumping 16 to 20 ounces per pump. All of that milk was going straight to the freezer."

Palmer gave her milk to pregnancy care center Guiding Star Mid-Missouri who knew of specific Texas moms in need. The frozen milk was packed in a deep freezer surrounded by long-distance ice packs on a truck and driven to small towns in Montgomery County, Texas.

Nicole Edwin, lactation consultant and president of Guiding Star Mid-Missouri, and midwife Terina Knarr delivered a total of 1,824 ounces of breast milk, Palmer's included, along with other baby supplies. Edwin was 33 weeks pregnant when they started driving south on Sunday.

"There are a lot of us moms who really just want to help each other," Edwin told USA TODAY. “We were especially looking for moms who were displaced and looking for milk that were affected by the hurricane."

They found two moms in need, including one with a one-month-old, and left the rest of the milk with midwives who had electricity and freezer capacity.

Edwin said what many don't understand is that not all babies who drink breast milk can nurse. There are a lot of medically fragile babies like Palmer's son who rely on their mothers pumping breast milk, Edwin said. Without electricity to power a pump and a freezer or refrigerator, there's a risk babies cannot be fed. Florida moms could face the same struggles as Hurricane Irma, currently a Category 5, heads for the Sunshine State.

Also, mothers under extreme stress, such as those In natural disasters, often notice a decrease in milk supply. The drop is usually temporary, according to La Leche League International, a nonprofit breastfeeding support group.

Guiding Star Mid-Missouri, which does not have the capacity to coordinate nationwide deliveries, is directing moms interested in donating milk to Mother's Milk Bank in Austin. The Human Milk Banking Association of North America, based in Fort Worth, Texas, also encourages moms interested in donating milk to find the milk bank closest to them for screening. The Texas Department of Health and Human Services offers a breastfeeding hotline (855-550-6667) for 24/7 breastfeeding support, including for formula feeding mothers who do not have access to clean water.
