Aw Sarah! Hang in there love! Myles went through the same thing at about that age too! I wish i had DH to help me settle him but he is a shift worker so i had to do all the settling! Myles can now be comforted but DH and my mum so dont worry about her not being able to settle for anyone else. She will begin to know who is safe, but maybe she just needs you now!
Hope you can realx and your precious baby girl can settle! Good luck x
