This week's sign is 'egg'.
Using both hands, hold up the index and middle fingers together (just like we did when we signed 'bunny').
Now place them in front of your body with palms facing the body.
Place the right hand on the left (crossing fingers).
Drop fingers down and apart.
Like an egg being cracked open.
Humpty Dumpty sat on a wall
Humpty Dumpty had a great fall
All the King's horses and all the King's men
Couldn't put Humpty together again.
