Shipmates toddle for Barnardo's.
The sponsored walk organised by Barnardo's Cymru took place at St Fagans National History Museum in Cardiff, and for the first year introduced a fancy dress theme of swashbuckling pirates.
Iona Needs, Big Toddle event organiser, said: "We would like to thank everyone for coming along. It was a fantastic event and a great outing for all the family.
"There was a fun atmosphere, with the children being very proud of their achievement and Big Toddle medal. It was so nice to see all the toddlers enjoying themselves whilst raising money for such a worthwhile cause."
Money from the event supports 43 projects throughout Wales helping more than 8,000 children, young people and their families each year. Their work includes supporting early-years work for children with physical and learning disabilities, autism and behavioural problems.
