What should my child wear to forest school?

All the children from year 1 to 6 have Forest school at some point during the year. 
They will come to school in their forest school clothes on the afternoon they have FS. 
Please come in old clothes as we get muddy and at times wet. We go out in all weathers so lots of layers and waterproofs are essentail. The children can bring their wellies in a bag to change into for the session.
