Throwing EVERYTHING

growingournest

Hi everyone,
Hoping you can help me with some tips on how to solve my toddler's throwing issue.  My son is 20 months old and sweet as can be, but I can't for the life of me get him to stop throwing things.  Balls are fine, of course, but food, toys (especially toys), you name it- he throws it.  This has started becoming a real issue because he attends a daycare with 4 other little boys, and he keeps throwing toys at the other kids.  His daycare provider tells me that he doesn't do it all day long, but at drop off and pick up time I notice it happening so much and I don't want him to hurt the other kids.  He also throws things at home- at me, my husband, our dog, etc.  We are incredibly quiet and laid back people, so I can't imagine he is showing aggression or seeking attention- so what is going on and how can I teach him that only balls are appropriate for throwing?  I have tried many approaches- telling him things like, "cars are for driving, not throwing," and showing him how I drive his toy car, taking the toys away that he is throwing, even time-outs.  Please, if you have had this issue with your toddler and found a positive way to redirect his or her apparent need for throwing, share your ideas!  Thank you in advance!
