When it finally happens at about 6-8 weeks, smiles make all the late night feeds and sleepless nights worth it. Seriously my heart glows with joy when I see Manu gazing up at me with his toothless grin and sparkly eyes. He is most smiley in the morning when Eddie is playing with him in bed or just before he latches on to my boob. Soooo adorable! Can't wait for the giggles.
