My 4 month old just cries around anybody else! Even familiar family members who she has always been around, this has been happening for about 4 weeks. She cannot be left with anybody but her dad! Any advice on how to get her better? I've tried them coming round to my house so she can get used to them in her own environment but no luck, no one can even hold her because she gets so upset she's inconsolable. We go away in 4 weeks with some family members and I am dreading it
