My little boy has never been a great sleeper, usually waking 2-4 times per night since he was born but recently he was starting to get it down to once and we have established a pretty good routine. When he does wake he is usually quite easy to settle and doesn't (or didn't) cry very much.
For the last 2 nights, however, he's been waking up constantly and literally screaming with tears rolling down his face and is almost inconsolable. He eventually settles on one of us and will sleep for up to 2 hours but wakes if put down and the whole thing starts again. He's been his usual cheerful self during the day, although a bit crabbier around nap times. He hasn't got any teeth yet and there are no signs of it being teething.
I've just gone back to work 4 days per week (this is my 3rd week back) and we've had an unfortunate run of illnesses (colds and stomach bugs) so not sure if this has anything to do with it. I'm still recovering from illness and so sleep-deprived I'm really struggling to be engaged at work.
Does anyone have any advice?
