Hi, I have a little girl who has been in a night time routine since 3 months and apart from teething has always gone to sleep without a problem, however the last 3 weeks she has started playing around at bedtime and not going to sleep. We've tried cry it out which doesn't work. She just cries bloody murder for hours. We've also tried increasing her daytime nap and also cutting it down. None of it seems to work. She's not going to sleep at the moment until earliest 8.30 when before she would be sound asleep by 7pm and sleep through til 7am. I thought it was related to teething but for 3 weeks?! Has anyone been through this? Or got any ideas on what to try?? Thanks very much :-)
