Hi everyone my 15 week daughter, never sleeps during the day and wakes up a lot overnight, all normal for her, since yesterday morning she has slept most of day and night, which is very unlike her, She is on lactulose as she isnt pooing very regularly (she isn't in any pain from this) help a worried first time mama! Any ideas? She will wake for a feed but not as regularly as usual but go straight back to sleep
