There's nothing to worry about ma, the baby will soon outgrow it. My baby used to be like that b4, if u sneeze, cough, clap or any kind of sudden noise she gets shocked and starts crying even whenever we go to church n people shouts amen or halleluyah, na crying galore but now she has stopped getting scared at every little thing. Instead of crying, she smiles now. So ur baby too will outgrow it as time goes on.
