Advice please! We have a 13 month old and basically overnight she has started crying hysterically every time we put her down in her cot for a nap and also sometimes at night. We rock her to sleep most of the time and she’s fully asleep on us but as soon we we lower her down, ping! She’s awake and screaming hysterically, standing up instantly. Before this she would 99% of the time roll onto her tummy and go to sleep. Not sure if it’s teething, separation anxiety or a combination of both but it’s exhausting, the other night it took us from 8pm until 1am to get her to actually settle and then she was up at 7am so she’s not getting enough sleep. She’s showing all the sleepy signs that she’s ready for sleep but honestly her routine is a bit out of the window due to her fighting it all the time. Advise would be greatly appreciated! Thank you!
