Afraid of others

Brooke

My 6 month old doesn’t like to be held by others — only my husband and I. If we give her to my mother or sister-in-law, then she starts to cry. She didn’t used to be like this! My mother and sister-in-law live in the apartment above us, so my daughter has been around them since she was born, and never had a problem until recently. Please tell me this is a phase.
