As you look at my site you can see how much I love being an aunt. Each year I take each niece for a week of adventure and fun. (Don't worry little nutter butter my sweet nephew as soon as you turn 5 you will get a week of your own.).
I like to send them an invite and build the anticipation. One year I made an advent calendar so she could count down the sleeps (as she calls them) till Annual Auntie Week.
