My ds is now 16 weeks and hardly ever makes any noise, apart from crying of course! I keep reading that babies should be gurgling, laughing and cooing by now, and he doesn't! He does make little noises, almost like humming, but that's it. My dh and I are from two different countires, so speak two differnt languages to our son. Would this make any difference? Is he behind in his development if he's not gurgling/cooing or laughing by now? Sorry, it's propbably just 1st time mum worries, but would like your opinions.
