Little M will be 7 weeks tomorrow and he is becoming quite interactive. He has been smiling for the past 2 weeks, mostly for his big brother. I don't know what it is he finds funny in him but when Big M dances around like a fool and talks to him, he just can't help himself. But lately, if he's in a good mood he smiles instantly when you talk to him. He even does it with strangers (Big M's teacher).
And what's up with the eyebrows? Daddy said it must be a male thing. :)
