By and large, our 20MO has had a pretty good bedtime and reliably slept through the night since about 13/14 months, bar a couple of sleep regressions. But 2 weeks ago she started waking up once a night, and then twice, really upset, and that was manageable as we just went in and gave her her dummy back and had a cuddle. She's then gone back to sleep.
A few nights ago this got considerably worse: she wakes up hysterical but when we go in to soothe her she can't be comforted - she pushes us away, screams, gets all hot and bothered. It's now started happening at naptimes too (refusing them) and we're feeling emotionally fraught as she is just so upset. Would love any advice from anyone who has come through the other side.
Before this she was sleeping for 2 hours at naptime from around 12 or 1230. And sleeping from about 7.15/7.30pm and then needing woken up in the morning at 7am.
