With the controlled crying, did your babies scream the house down? I have let her cry, pat her at increasing intervals only to have her scream more when I pat her. I've also shut the door and let her scream (sometimes for an hour), thinking she would eventually fall asleep, but she doesn't.
Do I just keep trying longer? And is the high pitched screaming normal?
By the way, she is waking up several times at night now and not going back to sleep without feed/cuddle so I really need to get into a routine. Thanks for the previous advice.
