1,2,5,6

Little Man will not use the number 3 and 4.  He can count to 10, sometimes even 12 but he omits 3 and 4.  So we sing a song (from Sesame Street (thanks Italian Mom)) called 1234.  Obviously it goes something like 1,2,3,4 I love counting, counting to the number 4.  He looks right at me and sings 1,2,5,6, counting to number 5.  I think this is on purpose now, I think he is playing me.  I think that the crazy part is that he might even be smarter than me.  Maybe 3 and 4 are just extraneous numbers or maybe the omission is a symbol of how he is asserting his independence.  Whatever it is, I cannot get the boy to use the numbers 3 and 4.
