I also have an 8 month old. At the moment she seems to really love playing with balls - she can roll them around, pick up and throw to me which she does for ages without getting bored. She also seems to like any toys that make heaps of noise ie crinkly or rattles. She also likes to bang things together to make noise like blocks and kitchen utensils etc.
It is also good to alternate toys regularly to keep your baby entertained.
On the food front, my bubs really loves cauliflower with white sauce and a little grated cheese, anything with natural yoghurt in it, mince with a little gravy and vegetables mashed together, rusks with vegemite and pieces of bread.
Hope this gives you some ideas!
