Hiya, I started with soft finger foods such as cubes of chedder cheese, sliced up banana, but also rusks and Heinz Biscotti are good finger foods as they melt down very quickly. I cut toast into soliders (about 4 to a piece of toast) that was very easy to eat and suck for my lo! I just kinda guessed at the size, anything I thought my lo could handle well. I also cooked up fingers of veg to soften them and my lo was ok with those. (Courgette, carrots, sweet potato, potatoes) Also small pasta shapes (the ones they use for soups) mixed with tomato sauce, very easy to eat but very messy!! lol!
Hope that helps!
