Speech pattern

I have a two year old boy whose speech has taken on an odd characteristic.  He switches certain sounds around.  For example:  he calls his Daddy, dayya.  We keep saying Daddy to him but he repeats the word switching the last two sounds around.  His name is Malik and he calls himself Amick.  He has a toy drum.  WE have noticed that he watches TV and will repeat sounds like drum beats exactly opposite of what he hears.  He will play the last sound first and everything in reverse order.  It is like sound dyslexia.  HAve you ever heard of this problem, or is it a problem?  Thank you for your help.

I don't know if this represents a problem - there is such a wide variation of what is normal in children of this age. It would be prudent to check with a Speech/Language professional to be on the conservative side.
