Babies are adorable and charming, but some of them have stranger-anxiety, and you can notice it when your baby is around 6 -9 months old.
This is the reason why your baby can scream or cry in fear when she meets new people or, even, sees family members or relatives that she doesn’t see every day.
In these moments, the best you can do is stay close to your baby.
Keep her in your arms, explain to the new people that the baby is a bit nervous and ask them to approach her slowly and not get to close or try to hold her until she feels comfortable with them.
If you explain these things calmly and relaxed, your baby soon warm up to her relatives and smile and play with them.
