my DD is 18 months old and for the last month her day sleep has been all over the place. Once she transitioned to one sleep around 16 months she slept an hour and 20 minutes and still had a 7pm bed time and slept through.
now she will either not sleep, sleep for 20 minutes and wake up crying and inconsolable, 40 minutes and wake up happy or again crying and inconsolable, an hour and crying and inconsolable, an hour and crying but back to sleep for another hour, an hour 20 minutes and wake up happy or 2 hours and wake up happy.
she self settles and has done for 9-10 months.
im not so concerned its different lengths of time as she's still sleeping through, but I'm concerned at why she's waking up and crying inconsolably and needs to be cuddled for 5-15 minutes before calming down.
There's a thermometer as part of her monitor and I know the temperature is ok. She eats lunch at 11:30 then down at 12, so she's not hungry or thirsty, she always has a clean nappy.
Is there such a thing as day terrors?
Has anyone been through this and can offer any advice at what might be wrong?
