HEY! Isn't That What i Usually Say?

Little Grace has problems pronouncing some words.  For instance, yellow she will pronounce it as ya-low, Mickey Mouse as Mimi Mouse, Water Bottle as bottle bottle etc.. 

Yesterday, she took out Nick's pencil case and asked me "what this?"  I replied "pencil case". She went "orhh....." then she walked away. A minute later, i called her back and ask her what is this (referring to the pencil case) and she went "look at my mouth, look at my mouth (she points to her lips) and she said PENCIL CASE" clearly.. 

HEY!! Isn't that what i do when she cannot pronounce words clearly? Hmmm...  I should have told her to her that's strictly "reserved" for mummy to use only!
