I totally recognize the sleep deprived  but undeniably too deliriously happy to care look about this new daddy.

Big sigh!
Those days are long gone for us here but oh, how I do remember the amazing quality of that love when it first hit me 14 years ago. 
It is maybe as close to perfection as this world gets. 
Though I don't have grandchildren yet...I hear that is when you really learn about perfected love!
