This is all I can think of for now, I wasn't sure how long you wanted the wording to be.
I am sneakily already looking at birthday ideas.. I'm thinking we will need to get invites out relatively early for a January birthday with the holidays etc. or at least that's what I tell myself so I can start planning
You're invited to a birthday
Because Mila's turning three
With arts and crafts and dress ups
What fun it will be
The venue is Te Papa
So come and celebrate
We hope that you can make it
So please save the date!
Date:
Time:
etc.
A day is coming, we hope you're free
It's Mila's birthday and she's turning three
or
We're jumping for joy and shouting with glee
It's Mila's birthday and she's is turning three!
