My dd (almost 2) has always been a brilliant sleeper and she loved to go to sleep and will ask to go to bed. (Sorry to those with poor sleepers this isn't meant as a brag but just to explain that she was naturally a good sleeper from the start.)
Since around 18 months she has been doing 7-7 with a 2+ hour nap and on nursery days doing slightly longer at night but with less nap. Recently, she has suddenly stopped sleeping and will sleep 8-6am if we are lucky and sometimes has very little naps. I have had lots of excuses such teething, illness, light mornings (now got blackouts which helped for a couple of days), excitement of holidays with cousins but it is now been going on over a month and there is no reason now for the lack of sleep. She has also got very upset about going to bed and will get very upset at story time before bed. I initially tried putting her to bed earlier but she will just scream and get hysterical in her cot.
Is it possible that she suddenly needs alot less sleep? She doesn't seem tired but she has gone from having 14-15 hours a day to 11 hours overnight.
Anyone got any ideas about what is going on? Also, what to do? I don't mind her going to bed later or having less nap but hate her getting upset at night.
Thank you in advance.
