Its a rite of passage.
They are growing up.
My daughter started at 3 years old.
My son started just this past Feb. He is 4.
Its sad sort of, seeing them grow up. But it is a real happy time too.
My kids LOVE preschool. It is a great time for them.
My kids were ready for it.
They adjusted just fine.
No crying.
Just happy.
When they are at school, it is my time to myself and it is still very busy. But it is great that way.... because I can get things done, just myself and my own train of thought.
A nice balance.
But sure, I miss them and it is bittersweet, because they are growing up.
