How many words should a 10 month old say?

Je

FTM so I'm not sure. My LO only says Dada consistently and knows what it means. He has only said Mama a handful of times but it's slowly happening more often now. He tries to mimic words but he doesn't say them on his own. He knows what a lot of things are. If I ask him where his water or teddy is, for example he will point at them or go and grab them. Is he where he should be at this age or should he be saying more words? Thanks!
