I don't know if it's just me or if it's something that all mothers do.
Since my little boy came into the world, I find myself singing songs and directing them all at him. When I was a younger, more starry eyed girlie, the songs would automatically bring my significant other to mind. I would sing along to soppy love songs thinking only of him.
Now I think of my little boy who truly is the 'sunshine of my life'
