i hate to say this but 4's are no better... uhg, i babysit ALOT and everyone one who doesnt have kids or babysits rarely thinks its better to watch the toddlers and up.. i say no way, i love them when i can carry them around, the only words they can say is "whaaaaa" and we can take naps together! :P
i had two girls to watch and all i had to was wake up with them in the morning... thats all! but they seemed to make it a much harder task! i look away for one min... one min.!!! and i had thier mom make up all over the walls and mirror and them... so i have to clean them up and get them ready for school in 15 mins! (btw they were 4 and 6)
then another time i had 5 kids!!! going by the oldest to youngest : 12 year old boy, 10 year old girl, 9year old girl, 7 year old girl, and a 3 year old
the 7 year old was my fav. she loved me to death... she would follow me around and try to be just like me

the 10 and 12 would play with eachother so they wrere good. then there was the 9 year old and the 3 year old... OMG! LOL
well i was fixing dinner and all the kids were watching tv (except the 7 year old.. she was helping me make dinner, god bless her) and i was watching the food and then i see the 3 year old walk up to me with bronze liquide make up ALL over him. i was in shock.. then i followed the hand prints! brown hand prints on the parents white walls, thier white down comforter, the white doors! it seems the 9 year old went to play with the make upa and the three year old followed, from there i have no clue what happened i just know while everyone ate i cleaned it all up... some of it just wasnt going to come off.. i felt AWFUL.
