I have a 7 month old baby who for the last month won't sleep more than a few hours at s time at night. She is BF and only has one feed a night so she isn't waking up hungry or expecting milk. She settles herself for naps and at bedtime but can't resettle hersslerself when she wakes up. She has 2 or 3 naps a day, without around a 2.5 hour wake window between each nap and slightly longer before bedtime. She's a very happy baby during the day but so unsettled at night. Any advice on how to get her to sleep for longer chunks of time?
