Same here..... DD is almost 19mo. It all started about 5 days ago. She cried and cried when I left the room. So we did WI/WO. It didn't work... she cried until she threw up
She is fighting nap as well. Totally a sleep monster.
She wakes up and cries, screaming "scared!"
The only way is for me to lean down and cuddle her. Once she knows I'm there, she stops and goes back to sleep.
I read in a book that toddlers develop sleep problem (fighting nap/sleep) around 20mo. Is it true? I hope this is only a phase..... she is teething and has runny tummy
