at what age/month did your baby...

respond to his/her name my son is 10 months and i will call his name and he won’t look but very few times he’ll look if i say his name a little bit louder ? is this normal , these passed couple of days i’ve been very worrisome about motherhood and making sure my baby is reaching all of his milestone i’m 21 so i’m young and everything is still new to me , i get teary eyed because i just want to make sure i’m doing everything right and he’s growing fine 😥😥
