3 month old got separation anxiety?

Jessica

My baby girl is 3 months ... she is always such a relaxed baby, never had any issues. The past few weeks have been so different!

She literally screams the place down as soon as she is with someone she doesn’t know, but now even with my family (her grandmother) she is literally inconsolable untill I get her back and she will stop after a few minutes!!

Please tell me this will pass or give me ideas of how to stop it!
