Baby talking

My baby’s pediatrician said he wants her to be saying mama, dada and uh oh by the time she’s one year. But all she says is dada. She’s 10 months old. Is this normal?

ETA: She does babble a lot and she’ll say things like “Gaga”, “baba”, “yaya”, but hasn’t said mama or uhoh which is what her ped said he wants her to say by a year.
