About An Hour

This morning I awoke at 8:58 a.m. (which is rather late) to the sound of my little Stinker hollering "Mama" like he does every morning.  I walked into his room to see him standing up in his crib.   "How long have you been up, Turkey?" I asked.  Shrugging his shoulders "About an hour."  he replied.  I had to laugh because for a split second I checked his walls for a clock; like he can tell time.  He didn't have his normal sleepy face and sometimes he does like to lay in his crib for awhile before hollering for me; but for a whole hour.  Could he possible have the concept of an hour at his age?  He is usually awake a little after 8 a.m. every morning so his calculation seemed correct. LOL.  He sure does have us all wondering =)
