Madonna and her four children have visited the orphanage that kept one of her sons before his 2008 adoption from the impoverished southern African country.

Home of Hope Child Care Center director Lucy Chipeta says she showed Madonna and her son David his crib during their Tuesday visit to the orphanage near the Zambian border. Siblings Lourdes, Rocco and Mercy — who was adopted from Malawi earlier this year — joined their mother on the tour of the orphanage, where Madonna's Raising Malawi charity has built several new buildings.

Madonna and her children arrived in Malawi on Sunday. On Monday she broke ground at her charity's new school for girls.

About 500,000 children in this nation of 12 million have lost a parent to AIDS.
