I need help, the 4yo boy that I watch is afraid of my 2yo ds. Everytime ds chases him (4yo) he runs to the bathroom. I asked him just now why everytime he (ds) chases him he goes to the bathroom, his response was "I'm afraid he's going to bite me." However there are time when 4yo says "come get me" and I've explained to him in the past if you don't like him chasing you, don't tell him to come get you. Now I know that he most likely has told his parents that he's afraid of ds if he just told me.
My son has bit him in the past, but has stopped the biting (we figured out that he will only bite if he has his blanket, so we only give him his blanket at nap/bedtime).
How do I help a 4yo not be afraid of a 2yo? (Willing to answer any questions that do not involve any bashing)
