Not sure what is going on here - my normally settled and happy 5 wk old DD (ex bf) has suddenly got very unsettled - so far today she has only slept for max 15 mins at a time, cries almost as soon as she wakes up, and can only be calmed by feeding. Haven't been clock watching, but must have fed her 10 times since we got up at 8am (so 9 hrs!), for up to 30 mins at a time (although sometimes less). Is this normal? She usually only feeds every 2-3 hrs, and is quite happy and settled in between, and will sleep for up to 2 hrs at a time. Am getting worried that something is wrong, and not sure how long I can cope without her getting a decent amount of sleep.
