Oh Olive, that would be heartbreaking!! I don't have any answers but just wanted to let you know I have the opposite problem - DD struggles to settle for anyone but me! I secretly love it but it is a PITA at times.

Why aren't babies born with a translation button??

Just had a thought, are you still breastfeeding? I remember the midwives warning me that there would probably be times when DD would settle for me and not others and it was because she would be able to smell my milk and get frustrated. Is that likely?
