Sierra Strangfeld knew her son wouldn’t live for very long after birth, but she wanted to do something that would carry on his name for years to come.

Her son, Samuel, was born earlier this month with Trisomy 18, a genetic disorder that is caused by an extra chromosome. Most babies with the disorder either pass away in the womb or only live a short time after birth. Strangfeld told reporters she wanted to meet her son before he passed, so she was induced and was able to hold her baby for three hours. She said that Samuel was born with several of the physical characteristics associated with the disorder such as clubbed feet, clenched hands, and was all-around a tiny baby. However, Strangfeld was able to look past these imperfections and told GMA reporters, “He was perfect”.

Sam only lived for three hours, but Strangfeld felt the need to do something for others in his name. When she found out she was pregnant, Strangfeld made the commitment that she wanted to breastfeed her baby. When she found out that her son had a genetic disorder, she knew she would not be able to feed her baby, but stayed committed to her desire to breastfeed. After Samuel passed, Strangfeld pumped her breast milk in hopes of saving little ones in the NICU. She said that if her son had lived, he would have needed a long stay in the NICU drinking pumped breast milk. So, Strangfeld decided to pump her milk to donate to the hospital. She pumped for 63 days, accumulating 500 oz of milk. On Samuel’s due date, Strangfeld delivered the breast milk to the hospital and felt that her son was proud of her.

This generous act did not come without heartache or frustration. In her viral Facebook post Strangfeld wrote, “Pumping is not for the faint of heart. It's hard. Mentally and physically. And it's even harder when you don't actually have a baby. There were times I was angry because why did my milk have to come in when I had no baby to feed? Why was I waking up in the middle of the night for this?” Her motivation came from the love she has for her son and the drive to want to help other moms.

Since donating her milk, Strangfeld has started a fundraising campaign called “Smiling for Samuel”. She and her husband have been selling t-shirts and sweatshirts in order to start their own non-profit organization about raising awareness for Trisomy 18.
