When does ur baby speak his first word

Hi mummies. My bb just came back from his 1yr devepopment check at polyclinic. Doc asked if he has spoke his first word e.g. papa or mama specifically to us. We said no but he babbles & understands. Doc says usually first word at 12 mth. Feeling worried now. I read that boys are more likely to start speaking a little later than girls . May i know to all the boys mummies, when does ur bb said their first word meaningfully? (Not babbling)
