The boy's first word

Lately Simon has been getting more vocal and I love listening to him babble. For awhile now he's been saying 'dad' and I wasn't sure if he was actually saying it referring to Pablo but over the last few days when Pablo walks in the room or leaves the room, Simon looks in Pablo's direction and loudly says 'DAD'. Very clearly too I might add. My mom saw Simon do it a few times and she too is convinced that he understands that 'dad' refers to Pablo. Pablo, you lucky guy! Now I have to get Simon to start calling me 'mama' or 'mum' or whatever the heck he decides on. Can't wait!
