you say you've tried lots of things... but how long for? IME you have to be consistent. don't just try ignoring for an afternoon... do it for a couple of days.
if he throws something then say NO to him, loudly and firmly, in your most serious (scary) voice.
then put whatever it was back.
you have to keep on and on and on with the same approach. if you see him about to throw something don't cajole him or try to reason with himn... he is too little and he enjoys the attention.
again just say no, and take it from him.
just to say im not pregnant and my 22 mnth ds is doing the same and its driving me nuts too...hang in there.
hope you get savvy with the 'time out' thing in time.
id been thinking my boy was too young too but im going to give it a try.
good luck x
ooops the time out i use with ds i have used for about 6mths as he knows what he is doing is wrong but will push the boundaries. My DS is 21mths and we have a beanbag in the hall for time out. What i do is he will do something so I say no that is naughty, repeats it again so i say the same then on third go if he does it again then i say if you do it again then you will sit on your beanbag for being naughty. When he does it again then he has to sit on his beanbag in the hall for 1min. He actually wont move from the beanbag as it isnt used for anything other than timeout as i didnt want to confuse him. After a minute i say he can come back into the room and he does and 95% of the time he doesnt throw again...well that day anyway..pmsl
I think time out will work depending on your little one. My son understands a lot for his age so timeout seemed like a natural step in trying to reinforce good behaviour.
It was a cot in the living room for us, followed by baby bouncer in the cot, unfortunately. It was only for a while. Till dd1 got used to the fact that someone might get hurt by hurling missiles at them. Or walking on them.
