She has another two wobbly teeth that she can now get to work on. She excitedly shows me how much they wobble every day and if I promise to be gentle she lets me have a go too.
Within a few months she will have a completely different smile - a 'gappy grin'. She'll look just as beautiful as ever, but it is a sign that my little girl is growing up, which as every mum knows is a bittersweet emotion.
As I write this post Lily is wrapping her tooth in tissue and taking it up to bed to place under her pillow in hope that the tooth fairy will pay her a visit tonight. I have a good feeling that she will.
