How long have your LO's screamed for? Do they get to the drenched in sweat, looking likely to puke stage?
We've been having a few sleep issues and Monday night we resolved, there was nothing wrong, so to leave DD (almost 13 months) to her own devices. She screamed blue murder after after 10 minutes got to the aforementioned stage and we got her up. I just couldn't see her getting herself to sleep in that state so i'm just curious as to what others have experienced.
