Baby hates everyone

My daughter is 4 months and for the past week or so, she cries whenever anyone holds her or talks to her that isn’t me! Even people she is normally fine with, like Daddy (works away sometimes), Grandparents and Aunts! She cries if anyone even looks into her pushchair, acting like a diva! Is this just a phase?? Please tell me it’s just a phase 😩😩
