My Little Girl is 15 months old & for the past 2 weeks it has been impossible to get her to go to sleep at night ( it can take me anything up to an hour ! ) I have tried everything from changing her routine to keeping her up later nothing seems to work. She just seems to find anything to avoid going to sleep & now refuses to cuddle in & drink her bottle. Any advice would be greatly appreciated as am totally lost as what to do next.
