Some other ideas I had for socials. Not necessarily all important. Put the ones at the top that I think are really useful, ones toward the bottom are less useful.
handshake - for obvious reasons
fall - to fall to the ground at will
huff / puff - express anger
boo / scare - to shout 'boo' at someone
hop / jump / skip / trot - obvious
sniffle - when you have a cold, or have stopped crying
