Hello girls, do you think it's normal for a child sometimes not respond when called by name? Very rarely does he say yes, in most cases he remains silent, but hears when something is touched, I tell him not to touch immediately and he listens and doesn't touch. I see on the internet that they write about autism, we had genetic testing at birth everything was fine and in our family there is none of this, neither with me nor with my husband.
