Baby daily diet - is this about right?

I had a baby born early. He is now 9 and a half months, but should have been born later making him really only 7 and a half. I'm wondering if what he's eating is typically what a 7 month old would be eating or a 9 month old? Here is what he ate today: Breakfast - 3 tablespoons of porridge oats mixed with 100ml formula and a small banana mixed in(he left 7 teaspoonfuls). Lunch - 1 piece of cod, 1 medium potato and 2 handfuls of spinach mixed with formula and water to puree. 1 fromage frais. He ate everything. He also drank some baby apple juice. Dinner - 1 sachet of Ellas Kitchen baby food (7 months) of which he ate all, and some pureed pear with baby rice (he didn't eat a lot of the pudding - just a few teaspoonfuls). He also had some apple juice. Offered rice cake as finger food but wasn't interested. He also had 2 7oz bottles and three quarters of another 7 oz bottle.
