It started at around 9 months, a horrible high pitched squeal which goes right through me. Now he does it if he's excited, frustrated, bored, or just for the hell of it.
I hate it, I can't stand it and I have constant earache from it - how to get him to stop? I'm considering putting the travel cot up in the living room and plonking him in there if the shrieking starts.
I really don't remember this phase lasting more than a couple of weeks in ds1, who has to sit there with his hands over his ears when ds2 starts, or worse, joins in.. Help!!!
