Roller coaster Day

When Baby N's happy it's like the sun is shining down on just the two of us. But when he is sad or in pain from teething or tummy ache - then it feels as if I'm going through the 1000 fires of hell. I have never ever been a part of something/someone who has such an emotional hold on me. I feel absolutely useless when he looks at me with eyes full of tears and blessed by all the gods of the world when he smiles at me.
