First lady Melania Trump said on Tuesday her trip to visit children at a drug treatment center in West Virginia was "incredibly special."

"Today's visit to @LilysPlaceWV was incredibly special," Trump said, referring to an infant recovery facility in Huntington, W.Va., that treats babies who have been exposed to addictive substances while in their mothers' wombs. "Let us all find ways to help children grow into happy, healthy adults."

Trump also shared images of her interactions with patients and staff at the center on social media as members of the media were not allowed access during that portion of the day.

On Monday, Trump's spokeswoman Stephanie Grisham said 40 percent of infants born addicted to drugs are put into foster care.

"To help babies born addicted truly succeed, we must help their parents succeed," Grisham said. "(Lily's Place recognizes) that parents who are working hard to overcome addiction will encounter barriers and need support."
