My boy is 12 weeks old and is a happy, smiley boy. He engages socially with his eyes and smiles. He gets excited when I talk to him as he kicks out and his eyes light up. I have no issues with his hearing as he reacts accordingly. My only concern is how quiet he is. He hasn’t ever really cooed. I say that, he makes the odd noise here and there but nothing at all back and forth. I can spend an hour talking to him and he will just smile. It’s like his mouth moves but the noise won’t come out. Anyone else experienced this? He does t make noise for attention either. He will people watch until he’s fed up and then start getting fidgety and moaning. I’m worried it’s the start of a communication problem
