14 week old dd, have struggled with nighttime sleep for a few weeks now, tried the 2 hourly easy routine, tried a bedtime routine of bath bottle bed but nothing seems to help! She's difficult to settle during the day for any period of time apart from on car journeys or outside in the garden. Can settle her relatively well in the evenings with the bath bottle bed but only lasts for approx 2 hours then full on screaming fits for the next 2-4 hours n so on. Am literally at end of my tether does anybody have any suggestions?
