Yes, it is normal for toddlers to go through this stage. i have a 2.5 year old and have worked with toddlers many years. It takes consistent redirection and saying positive affirmations. Such as telling what to do more than what not to do all day because they will try it quite often.. It takes alot of redirection. I mean alot of redirection! Eventually they outgrow it but until then, keep redirecting to something positive and just keep teaching your child the positive things to do.. an occasional no is ok, but focus more on positive redirection. Good luck.. they will outgrow it in time...If they have the desire to throw, give him a ball to throw outdoors.. but it is normal for them to throw things and trying to hit... they are testing
