Baby noises.. normal?

My daughter is 9 months old and recently she’s always screeching, growling and grunting. She usually does it when she’s excited, but she’ll keep doing it over and over. she’ll make a game out of it sometimes, like if I make a screeching noise first, she will copy it and we will keep going back and forth. I plan to videotape it and ask the pediatrician at her upcoming appointment, but does anyone know if this is normal or do your little ones do it?
