The Doctor's cot
From Tardis Wiki, the free Doctor Who reference
The Doctor's cot was the cot in which the Doctor slept in during infancy, it had writing in Gallifreyan carved into the sides. He still had it stored within the TARDIS when he was in his eleventh incarnation.
He put the ganger-infant Melody Pond in it to rest after he had rescued her on Demon's Run. Upon seeing the cot, Amy Pond pointed out "the Doctor's first stars" hanging above the cot. (DW: A Good Man Goes to War)
