Mothers staged a mass breastfeeding near Parliament Square as the Extinction Rebellion climate change protests entered their third day.
Hundreds of women fed their babies outside the QEII centre to "plead for the lives" of their children.
Lorna Greenwood who organised the event, said:
One mother, Anna Warrington, arrived to feed her nine-month-old twins, Mathilda and Aubrey.
Elsewhere, elderly protesters were arrested outside Downing Street. Police led and carried people out of the main road in Whitehall, while onlookers sang and shouted "we love you".
Elsewhere tents remained on Horse Guards Road, Marsham Street and near to Parliament Square, despite rain and an increased police presence.
