its too early for time out or "quiet time". This is effective for those 2 or above 2 years old, I have wrote
an article on this. You can get some idea from
here.
seriously, he is alittle too young to understand what should or should not be done, even after punishment.
when he screams...go to him and say, "mummy don't like screaming children, please play with this...." pass him a new thing, need not be toy, it can be a bunch of keys or anything under the sun that creates some sound, and he have never played with before.
sometimes his screaming may just be an attention getter, then you need to ignore it. back to basics, you need to understand your child's behaviour. If he continues after 10mins, then go to him and distract him with other objects that can entertain him.
Never say "don't" to a child, read
my article on "why
'don't' never works on a young child"
just remove whatever thing you do not wish him to touch away from his sight. Out of sight is out of mind.
Hope this helps....
