Anyone have an 18 month old who has suddenly decided they don't want or need to sleep at night? My we girl has always been a great sleeper - usually 8.30 through to 7.30 am but this past week that has totally changed! She won't go to her cot at all! Even tried her in bed with us but that's no good either. She will eventually fall asleep, usually on the sofa, but it's not till at least 12 or after it then she is up again about 4/5am. Some nights she is running a temperature but the ibuprofen just seems to make her more lively. I'm starting to really struggle on 4/5 hours sleep 😴😴 just wandering has anyone else had the same problem and if so how long it lasted for?
