Babies and food

So my girl just turned 9 months and had her wellness check up yesterday and there's always informational papers they give out at each appointment. So, the one paper is talking about food and how 9 months old should be eating 3 meals a day. My girl eats breakfast and dinner (granted she feeds herself at dinner so half the food ends up on the floor) but i'm just wondering if anybody is actually giving their baby 3 meals a day already? For mommas that have done this before, if you aren't already at the 3 meals a day, when did you start doing 3 meals a day?
