When Ira is sleepy, he pulls his hair with his right hand and sucks his thumb. He has sucked his thumb ever since the day he was born and I would wager that he sucked his thumb in utero as well!
And I'm obsessed with Ira's hair and refuse to cut it (even though it could use a trim) because of this... Fresh out of the tub and a little bit of curl. Really, really hoping Ira has curly hair like Conor one day!
