2 wiggly teeth

yesterday as Zippy was admiring her teeth in the mirror she came to show me her 2 bottom front teeth. She said "these are my smallest teeth" very true.
I took a moment to look at them and asked her if I could touch them, and they wiggled.
I knew this was coming, I did not expect it yet though, she only turned 5 last month. aren' t they supposed to wait till they are 6 or 7??

I feel like it is taking us into a new stage. She will lose all those cute little baby teeth she worked so hard to get 4 years ago, and grow new teeth big teeth that she will keep the rest of her life.
