Girls, I can't anymore... I haven't been able to sleep for a week now I just can't fall asleep and that's it! Not even a couple of hours, but all night long. I doze off before morning, get up around 10-11 am and don't sleep any more during the day... I don't ask how you deal with this, it's unlikely anything can be done. But please tell me at least how long this will last ? Jokes about "until the child reaches adulthood" are not welcome ?
