I love that:

I can put her in dresses
I can do her hair in pigtails
She is obsessed with handbags and shoes
When she is cheeky and gets told off she comes and gives you a hug and a kiss
She is daddy's little girl but loves mummy
Only mummy is good enough to sing and dance to the Wiggles with
She loves her baby brothers and gives them kisses and hugs

Most of all I love that she will be my only girl and hopefully we will have a special mother/daughter bond.
