Is this normal behavior?

DS is 9.5 months and when I call him by his name he ignores me. He use to turn his head towards me but I guess for the last month or two I noticed that when I call him he doesnt turn. If I start to say dada or tata he repeats it so I know he hears me. Do you think he forgot what his name is even though I call him by it all the time and try to include Luka in every sentence?

Re: Is this normal behavior?

it could be that he is being stubborn.

antonios usually only turns if I call his name. He ignores other sometimes. Sometimes he ignores me too but e starts smilling so I know he hears me.

I usually call his name and wait for him to turn before I tell him something.
