DS (18 months) has recently developed a habit of throwing things, (food, toys, literally anything heavy or light). I know that this is normal. I know it's a developmental thing... But God, it's frustrating.
He's a big boy for his age (he wears age 3-4 clothes), so when he throws something it's done with one hell of a force and today he hurt his cousin in the process, (this isn't an isolated incident). I try to say 'No' in a firm voice and I remove the item after such an incident, but he just finds it funny. Sometimes he even looks at me before he throws.
I've tried reacting to it, not reacting to it, trying to distract him when I get the feeling he's about to hurl something.
What should I do? Please share some similar stories.
