Just that, really.
DS is nearly 1, we've done a mix of finger foods and mashed up stuff, but always tried to encourage him to self-feed as much as poss.
Now he loves banging his spoon in the bowl while I feed him, or taking loaded spoons and waving them around before putting in mouth. When he's had enough he has a tendency to throw everything on the floor, and often wants to hold bowls/yogurt pots/whatever so he can poke/throw it everywhere.
I don't really mind all this, food is for fun and all that, and I do say things like 'no, put your spoon in the pot, not your hand' and 'no DS you've thrown the spoon on the floor you can't have it back' etc. Largely pointless, IMO as I think he's too young to be table trained, as it were, but MIL has made some comments. Made me wonder when I should be worrying about trying to encourage table manners? Is it already too late?
