I would say Piglet has the hang of it now at 9 months. She can pick up and eat just about anything she wants, so I know if she's not eating it's because she's simply not hungry - but I'd expect her to eat at least something three times a day now (plus maybe a snack, maybe not). But it's only quite recently that she's got so competent. Certainly at 7 months she was mainly playing with food, and bits went down more by luck than judgement. Know what you mean about being fooled by big jars of babyfood - but then when you see how much of it doesn't go into the average baby, and how much goes in and comes straight out again...
