My dd is 5 months and last night she woke in the night for no known reason, maybe heat? She wasn't upset just unsettled and restless. She has a dummy to get off to sleep then drops it out after not long. Nap times she rarely needs it put back in after the first time but at bedtime it's 30-45 minutes of dummy back in before finally asleep enough to not need it back. In the night it was an hour and 3/4. Has anyone got experience of this and should we have a few nights of hell to hopefully cute this problem and shd will be able to settle herself or at least quicker if we have to go to her?
