Step 2: poke it
Step 3: pick it up and do a few trips towards the mouth, not quite getting it in.
Step 4: put it back on highchair tray.
Step 5: pick it up again and smash it on the tray.
Step 6: smear it on the tray.
Step 7: Chew a corner of it for a little while.
Step 8: Smash it again, and pull it apart so there are little pieces in a pile on the tray.
Step 9: Randomly wave hands around, so that some pieces fall on the floor.
Step 10: Pick up a piece in each hand, wave them around, then put one in the mouth.
Step 11: If still hungry, repeat steps 2 to 10 a few times.
Step 12: when no longer hungry, systematically 'clean' highchair tray with a remaining piece, or drop each piece - as pincer grip skills allow - on the floor and have a look to see what they do there.
Step 13: be placed, fully clothed, in bath.
