Madonna and her children visit Malawi orphanage

Madonna and her children were greeted with song and dance by hundreds of orphans on Wednesday, when they visited an orphanage in Malawi.

The pop star said she was happy to be back at the Home of Hope orphanage, where she adopted her son David Banda, in the western district of Mchinji near the border with Zambia.

"I'm happy that David is back to see his brothers and sisters," she said.

David, now 8, was accompanied by his sister Mercy James, who is 8 and also adopted from Malawi, and their siblings, Rocco and Lourdes.

Madonna adopted David in 2006. On Wednesday he was taken to his former crib, which has been preserved in his memory.

It wasn't known if the family would also visit the Kondanani Children's Village, where Madonna adopted Mercy in 2009 after a protracted court battle.

Madonna and her children will visit a pediatrics hospital in Blantyre on Thursday, and another orphanage Friday.

The singer arrived Monday in Malawi to visit projects she has helped with. Madonna initially planned to build a $15 million 500-bed Raising Malawi Academy for girls, before changing plans to help fund several community schools.

Madonna is also parting ways with an abstract French painting she's owned for more than 20 years to support educating girls in Afghanistan, Pakistan and other countries. Fernand Leger's "Three Women at the Red Table" is expected to bring in $5-7 million when it's offered May 7 at Sotheby's auction house, with all proceeds benefiting the Ray of Light Foundation. The pop star said in a statement that she wants "to trade something valuable for something invaluable" in countries where female education is rare or nonexistent.
