My 16 month old has stopped sleeping properly. She is struggling to get to sleep talking, singing and moving around her cot for at least 2 hours before sleeping but trying to sleep in between all this. She is also waking 2-3hours earlier than she usually would. Nothing has changed on night routine or her nap schedule ( still napping fine). She has also recently started having bad tantrums since the sleep issues, she has always had tantrums from being about 10 month but they are extreme now to the point we’re struggling to leave the house. Has anyone experienced this or have any advice what would help please?
