Should I be worried

lady A

I am a first time mom, do I need to be worried? My 11 months old answers his name when he feels like it. Sometimes he completely zooms out when I call him. He can clap his hands when instructed, follow simple commands like stop, come and sometimes look at something when you instruct him to. He says dada, mama, Gaga and baba. He does not call us by that.
