Advice and tips please

My baby just turned 6 months & she hasn’t really seen much family because of COVID & the holidays is coming up so we were planning on having some family over but everytime she gets near a family member she bust out crying 😭😭 like tears and all even if I’m holding her, I know it’s going to take time but I just would like advice and tips on how to help her get used to them better.. I know she’s a baby and she doesn’t know them so ofc she’s scared but I’m sure my baby isn’t the only one who’s like this so please advice would be great.
