I have a 2.5 year old who has never slept well. She'll sometimes sleep through for a few months, but generally has woken up once or twice a night since birth.
We currently go in and resettle her and leave. Sometimes we sit with her for a few minutes but we don't stay until she falls asleep. We keep it quiet and calm and boring. We don't go in until she's been crying for a few minutes.
Any tips?! I'm so fed up of broken sleep.
