My10m old babyboy makes grunting noises while playing. All milestones met and spells out mama dada also. Is the noise making normal?

Completely Normal. It sounds like your 10 month old is hitting all the appropriate developmental milestones. Saying mama and dada is right on time. Other noises like grunting and babbling are normal as well. Continue to engage your son and read him lots of books to encouraged language development. Enjoy every step, it goes by fast!
