Midwives in Argentina have bared their breasts to protest government plans to restrict home births.

About 50 women joined Thursday's demonstration against a health ministry proposal to cap home births that was organized by Argentina's Midwives Association.

Some protesters had their backs painted with a sign reading: "I'm free and I choose to give birth at home," while carrying toddlers in their arms.

Traffic in some areas of the iconic 9 de Julio avenue in Buenos Aires came to a halt as surprised drivers watched marchers who bared their breasts painted in colors and shook their hips to the beat of a drum.

Midwives, pregnant women and doctors joined the demonstration in favor of home births, a practice that has been increasing in Argentina and the rest of the world.
