8 month old not babbling consonants!?

Becca • ✨✨Mother of 2 ✨✨
My son has been mastering his crawling and pulling himself up, and he has even tried walking along our couches. He seems to be developing fine in these areas, but I have a little concern, he has yet to babble any consonants like mama, dada, gaga etc. my question is have your little ones started to babble? Should I be concerned?
