Mine are a little older, but we started off with:
Playing with playdoh-making stuff, adding glitter, pushing macaroni into it etc...! (I have a good recipe if you are interested!)
Sponge painting/ hand painting (i covered the whole table in lining paper-more chance of getting paint onto paper!) Also painting with brushes, cars, potatoes etc! (Also can be done on fabric for a nice keep sake!
Sticking anything onto paper (quality street wrappers, feathers, etc) with homemade glue!! I used to get quite a lot of stuff from the early learning centre, but now i mostly pick stuff up now and again and keep in a box as i am going along!
Hope this helps, i will re post if i think of anything else!
