As usual, I am going to say the opposite of everyone else. I am just strange, I know.
I liked my kids as teenagers - thought they were fun and it was cool to see them become individuals.
I do not think they grow up so fast. I thought it took forever and have never understood people who said it went too fast.
I have never spent one minute wanting them to be little again.
And heck, I'll throw this one in too so you really think I'm crazy - I think girls are easier to raise than boys.
I have four - 2 of each - 17, 19, 21 and 24.
