Throwing Objects

Hi everyone. I just found this group, and I'm so excited that it exists. I have a 17 month old son. I'm already feeling a bit lost in my parenting journey. He's been throwing things in the house, and it's almost anything he can get his hands on. I don't want to be a parent that yells or intimidates; I usually do fine with the redirecting attention approach, but with the throwing he goes from fine and playing to launching whatever he's holding across the room without any warning. Any ideas on getting past this phase without being a hollering momma? I know he doesn't know better, but I need to figure out how to teach him.
