From what I've read, apparently fussiness in babies peaks at 6-8wks. If you had what you thought was a relatively easy first month and encountered super fussiness around this time, how soon did things start to get better?

Things were starting to get good with S at around 4-5wks and then a week and a half ago it was like someone flicked a switch and she woke up a different baby. Lots of crying and general fussing every single day.

She's 7wks now. Please tell me this gets better soon!
