Hello ladies I’m a FTM and I was just wondering what sign you noticed that lead you to believe you child has autism? My son is just turning 1 . My son flaps his hands sometimes when he is playing not all the time . It’s rare but I’m just worried, some other things Is he has been hitting milestones before he is supposed to but the only one he isn’t hitting is talking all he says is dada and baba and that’s it . Mainly baba and he doesn’t always respond to his name . He does most of the time but sometimes he doesn’t . Could these be signs ?
