Dear K.,
I'm a 41-year old mother of 2 children and expecting me 3rd. My son is almost 7 and in 1st grade. My daughter is 4 and just started VPK. My husband is a Lt. Colonel in the USAF and is the oldest of 5 children. I'm the youngest of 3. I started babysitting at 15 years old and started teaching piano lessons to kids when I was 16. So, I've been around children for over 20 years and have been resposible for their welfare for long periods of time.
My son was NOT an easy child and STILL has his moments. I thought that between the ages of 2 and 5 I was going to end up running away from home :-) I took him to psychiatrists, psychologists, the pediatrician, talk to my Mother-in-law (who, in my opinion, is an expert on raising children since she raised 5 good ones - 2 boys and 3 girls who were all born back-to-back w/ a set of twins last). Let me tell you that this situation is not easy for a babysitter. You MUST get the parents permission to punish this boy with Time-Outs and then Spanking for really bad offences such as you have discussed in your posted dilemma. Hitting, purposeful destruction of property, blatant disrespect - these are all corporal punishment behaviors. Save the Time-outs for lesser offenses such as not-sharing, temper tantrums, etc. Also, find a place for time-out where this child has NOTHING to do but sit and think (no TV, no toys, no friend to talk to). If he does not stay in time-out, this is a corporal offense.
I know that some parents do not believe in spanking and maybe you don't either. I can tell you from my experience that unless this child has some level of fear of you as a grown-up and an authority figure, this will never stop. This boy ended up this was because his parents let him rule the roost. He apparently never gets punished for his behariors at home.
The next step is, after a couple of weeks if his behavior does not improve with good, old-fashioned punishment for bad behavior, then you need to speak with his parents again about taking him to the pediatrician to be evaluated for ADHD and possibly autism. Children who have these disorders and frequently violent and do not respond quickly or not at all to regular punishment techniques. This boy may need therapy and maybe medication to help him control his behaviors. The determining factor here for the bad behavior part is - "Can the child control these behaviors by himself or does he need medication to help him?"
If the parents are not receptive to the punishment that you need to use, drop the babysitting job. It's not worth the damage that it WILL do to your daughter (not to mention you). Your daughter will absolutely pick up some of these behaviors. I know this because my daughter mimics my son. I have been told that this is normal for children to mimic each other. Example: Over the summer, I put my son in a Summer Camp. By the end of the first week, he had not only gained 6 pounds but his attitude at home was horrendous (sp?). He was back-talking me, never doing what I asked anymore and beginning to pick on his little sister again. Needless to say, I had a talk with the Summer Camp Counselor about this. She informed me that Trey was hanging with another boy who, was not only obese (so they were eating together and Trey was trying to keep up, I guess) but this other boy was a holy terror to deal with. So, it didn't take long for my son to try to act like this boy. The following week, my son went to Tae Kwon Do Camp. No more Summer Camp at the other place for him. It took me about 3 weeks to break the behavior pattern that only took him days to learn. Another example: My daughter starting biting her nails once she observed my son doing it. The problem is, I broke my son of it, now I'm having trouble breaking my daughter from biting her nails. She also heard about him toileting in the tub during bathtime on several occasions because she overheard him getting punished for it. Guess what? For the first time ever, my daughter toileted in the tub just after this. I guess she was thinking "He got attention for it, why don't I try it?" So, negative behaviors are VERY EASY to transfer from one child to another. It's the positive ones that are harder for them to pick up. It takes longer.
Anyway, hope that this helps at least a little. I don't know how you can watch this brat (because that is exactly what he is if you don't mind me saying so). With all of the negative behaviors that I have experienced with my own children, they have NEVER inflicted these on a baby sitter. The sitters that I have had over the years have always given them rave reviews (much to my amazement!). I always wondered why they didn't act that way with me.
