Classes / activities for toddlers

[reren]

My nearly 3 year old is at nursery 3 mornings a week - but I'd like to organise a class or something for him to do one of other mornings or afternoons (ie Monday or Tuesday). I've looked on Ed- tots and know about some of the drop-in playgroups - but I wondered if anyone had any recommendations on classes? Would love him to do an arts and crafts class for example - but can't seem to find? Has anyone any experience with the eos dance school? Too prim and proper for lively little boy? He loves dancing - but don't know if ballet is quite his scene yet...
