Missing teeth, and growing up...

This morning my 4y/o son accidentally headbutted his 7y/o sister, causing one of her wobbly teeth to prematurely fall out. She was already missing her 2 front teeth, and now with another one gone, she's looking like a true Collingwood Supporter!
The cool thing about it all is this though - those teeth need to come out! I'm no dentist, but we simply call them 'baby teeth'. Those baby teeth need to come out to make way for .... 'Adult Teeth!' Pretty soon in my daughters mouth, we'll start to see brand new teeth pushing through (hopefully straight and not requiring expensive braces work later in life!!!)
As followers of Jesus...disciples...there's a very similar thing that takes place in our lives. We need to do away with the 'baby' stuff of faith, to make way for the more mature things..
1 Corinthians 13:11 "...When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me."
So this morning, I'm thinking to myself "what childish ways can I put behind me to make way for the more mature things..?"
What about you?
