DS is 15 months and has slept through from about 8 months, although he's a bit of an early riser. Over the last couple of weeks though his sleep has got worse and he's now waking in the night screaming and taking up to 1.5 hours to settle. It's not consistent - one night he woke at 11.45 but this morning made it until 5am. I've had him checked out for an ear infection and his teeth don't seem to be bothering him and I don't think he's cold....
So - the only other thing I can think of is that in the last 3 weeks he has started to walk, talk and be very independent (e.g. feed himself). Everything seems to have happened at once and he is non-stop at the moment!
Did anyone else's DC react in this way to development? And will it just resolve itself? At the moment I am sitting by his cot until he goes back to sleep. He gibbers to himself and occasionally sticks a hand out and says 'Harroo!' which is very cute but we are all - including him - getting a bit knackered by it all.
