My 4mo ds is just starting to chuckle. We're still waiting for the hysterical giggling stage but he definitely laughs now. Thing is, I thought babies were supposed to LIKE repetition! Not mine. Something will make him laugh one time but if we repeat it he's like 'Seen it - what else ya got?'
The only thing that will induce repeated grins (he's very smiley) is counting to three very slowly (oh the anticipation - the punch line is always a let down though) or blowing raspberries. We're running out of ways to try and amuse him now. So, how do you make your babies laugh?
