Yes, pretty much what the PP said. At 9 months, he should have his pincer grip, so be able to pick up almost anything. We started at 6 months with toast with cashew butter, mashed avocado, mashed banana or hummus, rice cakes (with similar things on them), roasted carrots and parsnips, oven-roasted potato or sweet potato chips, soup with toast fingers, cucumber and melon sticks, fruit or savoury muffins (blackberry muffins, blueberry muffins, carrot muffins, spinach and feta muffins, etc). By 9 months, she was also having things like peas and sweet corn as she had a pincer grip and could manage picking them up, plus things that required more scooping, like yogurt, porridge, chunky soups, curry and rice, chilli, etc. which she'd scoop up with her hands.
