Attention Please!!

Alexander cracks me up. When he wants my attention he gets it by doing one of 2 things. 

Step 1 - Shout 'Maa. Maa.' until I respond.

Step 2 and the most recent - 'click' your fingers while clicking your tongue at me.

 
Today he did both while he wanted me to sing Humpty Dumpty for him. I don't know if step 2 is from us clicking at Chilli when we want her to come to us or where he has picked it up but it makes me laugh each time!
