I'm at my wits end. 11 week old dd screams throughout the day and when I say scream I mean hysterically. It can come from nowhere and for no apparent reason. It's ear splitting and nothing I do seems to stop it. She sleeps well, is feeding well and sometimes seems really happy and content. But then she'll scream out of nowhere and it's so distressing. I don't believe in controlled crying especially at this age but sometimes I have no option but to put her down in her crib and leave her for a few minutes because it drives me absolutely mad. It's almost like a temper tantrum (although obviously I know she's too young for this) in that it's frantic and seems to peak then calm down after what feels like several hours.
I really don't think she's in pain with anything but something must be causing this. My other children never did anything like this. Is it normal? Any advice would be good as I feel so stressed and panicked when this happens that it's making me not want to go out.
