One of my favorite things that TJ says to me is when I sneeze. He stops whatever he is doing, looks at me with concern and says "You ok, Mama?" - he also says it often to me when I'm in the kitchen, usually cooking or cleanig, and he's playing in the living room. I never realized how much I say ow or ouch.
Each time I say it, I hear his concerned little voice, "Mama, you ok?".
Never fails to melt my heart.
