Ronan is responding to his name

There are so many things which a child learns when he is growing up. One among them is responding when someone calls out their name. Ronan started recognizing his own name. He has just completed 5 months. Whenever Ma, Pa or we call out his name, he turns around and smiles.
He has this cute gummy smile and what makes it even more cute is that it looks crooked as his face is chubby.
