Chelsea for the last 2 weeks has taken to opening her mouth for food, taking it off the spoon, looks at me, smiles then blows it back at me.

Whilst its funny the first few times....but after being hit 4 or so times its no longer a game nor funny to me. Im sick of getting sprayed with yoghurt and the like!

I tell her NO in a stern voice and take her food away. Wait 5 mins then try again...only to repeat the same thing.

How can i stop her from doing this or am i doing something wrong??
