Things that just kinda pull at the heart

The other night when I had picked my son up while I situated his pajamas in the crib to get him dressed.  I wasn't paying much attention what he was looking until he started making a little bit of noise and actively reaching towards something. 

I turned around to see what he was looking at and saw he was reaching for a picture of daddy.  I know he is at that age that he doesn't really understand what the sounds are, but the next thing that came out of his mouth was 'da,da,da,da,da'... 

This was the second time since my husband has been gone that he has done something that really just made me think about how much he may not understand the timeframe of how long daddy is gone, but that he acknowledges that daddy isn't here.
