Word of caution. I tried for 7months to curb a little boy was biting. I really wanted to try and try and give up. He was sooooo sweet. The parents were a gem. The hours were great. Always paid on time. Then one day he bit someone and "BROKE" the skin. I slapped myself and said "what the hell are you doing girl, they could sue if something worse came of broken skin. I realized all those months of trying didn't make a difference. I'm not saying don't try. Just know when it's time to call it quits. I terminated that night at pickup and the Dad was terrible to me.
