Momentum Children’s Charity supports families across South West London, Surrey and West Sussex whose children are facing cancer or a life-challenging condition. We provide personally tailored support to the entire family, both in hospital and at home.

We’re there whatever the outcome, for as long as we’re needed, so that no family has to cope alone. 


Our Pebbles

Our pebbles

When a child is diagnosed, we give them a personalised, decorated pebble, to accompany them throughout their treatment. To symbolise the end of treatment, they can release it from our boat into the river, hide it in the forest near our holiday cabin or throw it into the sea by our beach hut. Alternatively, they may wish to keep it forever.

£15 would give a child a special Momentum Pebble when they arrive home from hospital.
