WHAT???? No, this is totally NORMAL!!! Listen, your child is making sounds, is babbling a ton, and all that is perfect -- joyfully perfect -- at one year old!
Does your child point to things and make a sound (any sound)? Great! Is he watching your lips with interest when he's close and you're carefully enuncieating something interesting like his name? Woot! Is his receptive language starting to emerge, like if you say, "Where is your nose? NNNNNooose?" can he point to it? Wow, that's pretty cool for a 13 month old!
You can help him associate sounds with words with objects by repeating it (joyfully, excitedly, like you're introducing a young Hellen Keller to the world of words). So, like, he points to his milk and says "Ya!" and then you say, "Oh, you want milk?" point to milk "Milk? Say mmmmmmiiilk!" (and he says "Ya!") and you say, "Yes, mmmmilk! Milk!" Then give him the milk. "Milk! Yum, yum, milk!"
He'll be talking by three.
