He is not responding when I call him.. It is not always happening, sometimes he responds when he did any wrong thing I said no to him.. That time he looks at me he stops. But few times, even though I am very nearer to him also he won't respond to my words and orders.. His brother have 4.5 years old. He likes him very much.. Mostly, he plays with him like peekaboo games and train games.. So many of my relatives depressed me that, he is not responding when we call his name.. What is it ❓ is that ok. Like that they are asking me.. That's why iam frightening about my baby..
