Speech in 14 month old

My boy is 14 months old in a couple days. He says dada or even daddy constantly, he will also point at something he wants or thinks is cools and says “this” and then he says “uh-oh”. He will say “Hi” occasionally when FaceTiming someone. He used to say mama, but it’s almost like he’s completely dropped it and I wonder if it’s because I am with him 24/7.. He has a cousin born 8 days after him and he has so many more words than my little.

I just want to see what’s normal? Is there anything to worry about at this point? I narrate everything I do, we sing, and play, etc.
