13 weeks and was getting herself into a nice routine of feeding all evening then falling into a deep sleep around half 9. Last night she fed and cried and had horrid green manky windy nappies until nearly 3am. Thought it was because I'd had 2 strong coffees in the afternoon but no caffeine today. Today she's been fine but same again tonight only less bum action. DS was still screaming all night at this stage so I don't remember noticing anything different!
