In Alexandra Township, South Africa, countless kids flock into a courtyard for a bowl of hot cereal with woollen hats covering their heads from early morning chills.
Most of them have lost parents to AIDS, but thanks to Portia Mongake, popularly known as Mama Portia, they can have a meal or two each day.
After she left her abusive husband 16 years ago, Mama Portia found new meaning in life by assisting those who need help the most in her township.
Each day she feeds hundreds of children orphaned by AIDS -- from toddlers to teenagers.
The 52-year-old roars to life at dawn in a courtyard bordered by a church, a row of toilets and her own makeshift house to start preparing food for her big "family".
"The situation they find themselves in is very hard, and very painful. Those who are living by themselves, it's a problem, because most of the time they don't know where the next meal will come from," sighs Mama Portia.
"If there's no food here, then they will sleep without food."
Around 120 orphans come in for breakfast while twice that number show up for a late lunch served after school. Some eat there, while others take away to eat at home.
"Almost everyday, we eat porridge so that we have something in our stomachs because without anything in our stomachs, we can't learn, we will be lazy at school," says Sinah, 15, who will take away to school fruits and doughnuts.
Assisted by her daughter and a handful of volunteers, Mama Portia not only cooks but also helps the children with their homework and organises activities, thanks to donations from local companies and well-wishers.
"We are like a family for them," smiles Mama Portia, who says she draws strength from her deep faith in God.
She founded the "family" 12 years ago when a friend died of AIDS and she immediately took custody of her four children.
Her initiative is just one of many "mama" family groups that take care of children orphaned by AIDS in a country with almost six million people living with HIV and AIDS.
Statistics on poor children in South Africa are staggering. Some 11.9 children out of a total of 18.6 million live in poverty, according to UNICEF. More than a fifth of them go hungry.
Some 3.5 million of them are orphans, two million orphaned by AIDS.
About 10.3 million poor children live off government monthly stipends of 270 rands (32 dollars, 26 euros) each, meaning more than a million others do without.
"We haven't missed a meal since 2001," boasts Barry Moyle, a white friend who comes to give Mama Portia a hand. Companies and individuals donate most of the food as well as clothes, blankets and school supplies.
"By the grace of God everything comes, but we need to be organised," said Moyle, who plans to set up a proper foundation to help with fundraising.
Mama Portia's helping hand reaches out not only to children. She also organises support groups, such as one for women who are HIV-positive in this black township north of Johannesburg.
She has expanded her scheme to feed some 50 grandmothers, known locally as "gogos", who do not have anyone else to turn to.
"I just come here so the lady can help me, to give me something to eat. She has changed my life," says 75-year-old Tabia Mofulatsi before the distribution of fruit and the staple corn meal.
Still, despite winning an award for her work, Mama Portia faces immense challenges.
She was kicked out of her previous home by the neighbours. Along with her children and volunteers, she now squats in what was supposed to be a public garden next to church, nursery school and doctors' rooms.
She shares her two-room dwelling, consisting of a kitchen and a living room that doubles as an office, with several adults and 10 children -- and other creatures.
"I sleep here every day," says Sophie, Mama Portia's daughter. "You must come here and experience the rats!"
