Weaning at One - Birthday Present!

Valerie • Baby Girl Addison. One & Done!
My baby girl is 7 months and a champion nurser! I travel for work and it's sometimes difficult/stressful on her when I leave so we are going to stop nursing at a year old.
When do you begin the weaning process?
How do you begin? How long did it take you?
She currently nurses to sleep every night.
And sleeps through the night so I'm nervous to throw off her routine.
Since we started solids I've noticed my supply has gone down.
We also plan to celebrate her birthday at Disney World and it would be nice to not be nursing. 😁
