Oh wow and does that little man scream

He does it when he is excited, happy, angry, to get someones attention, at the dogs, at the door, at his dinner, when hes hot............. you get the picture
I tell him no firmly every time he does it but just just screams louder

Is he too young to understand yet do you think, wondering if just ignoring it would be a better plan and seeing if he just forgets to do it.
Anyone else had a screamer before? My other boys never did this, boy is this little man a handfull!
