3 kids and a Babysitter.

So I have been babysitting for this family for, I want to say 4 years, well anyways. Major changes have gone on since I first started.
1.) They use to have two kids (Ages 1 and 3)
2.) Now they have three kids and the youngest one just turned two. OMG!!! That went very fast.
3.) The oldest one now almost 6, use to just tune out the world, she would come across to you as a deaf child, and it was sickening, I didn't want to scream because that would make me feel bad, but what could I do? I basically sounded like a broken record as I called her name for what seemed to be the tenth time. Now she actually comes on the first call. Man I felt that I was a trainer for a new puppy.
4.) The Middle Child always had a anger issue, it seemed like you never could make her happy. I swear nothing made her happy. She was always stomping her feet around, somedays it would seem like she would finally break it. But she never has.<--Which I am grateful for. :)
5.) The baby is too quite, and she is very sneaky. You can't turn around from looking at her. I find that she likes stairs. Due to the fact that she is always on either the second floor stairs, or the basement stairs. She has scared me once where she did fall down 3 steps and hit her head on a floor. But she is fine. :)

My whole life was dedicated into raising these kids as if I would be raising them as my own.
No I dont have any children, I dont have time, nor do I want to have any at the moment, I still have my whole life in-front of me, and I dont need any kids to slow stuff down.
I love Children and I think they are wonderful. :)

Thanks
SB.
