wee is actually a Scottish language that they speak.
They mean it as small/little.
There are some exmple:
I might be a wee bit late, please just wait for me.
You're looking a wee bit tired, are you ok?
I'm a wee bit hungry, fancy getting a sandwich?
or you can use like...
When i was wee, i use to ...
It means when i was young.
