I love this quote. It comes from a blog I really daily called Rude Cactus. It is all parts of awesome.
Replace the words "Father" and "Dad" with "Mother" and "Mum" - and this is exactly I how I feel every single day. I cannot believe I am a mother of two gorgeous girls, and I love them both so much it surprises me. You never run out of love to give to these little people you create.
