is just weeks away from becoming a dad
, so it's only fitting that the singer and UNICEF ambassador is blogging about children's issues.
Aiken, 29, recently visited Somalia and Kenya, and has been blogging about the trip on the UNICEF Web site
In his final posting, Aiken writes how violence during the country's election earlier this year left thousands of children homeless. And even though the unrest has decreased, many of the kids have not returned to their schools.
"Getting children back to school is vital for their protection, and helps build a sense of normalcy in their lives," Aiken writes. "The re-establishment of schools in the most difficult circumstances is a testament to the commitment of UNICEF and to Kenyans."
Aiken continues, "Every child has the right to an education. Education transforms lives and breaks the cycle of poverty that so many children are caught in. And an educated child will make sure his or her own children receive an education too."
Next up for Aiken? Fatherhood. As PEOPLE confirmed in May, Aiken artificially inseminated music producer Jaymes Foster, whom he met when he was on American Idol
. Foster, the sister of legendary music producer David Foster, is due in August.
