Sleeping through the night (well, kind of)

Titus has been sleeping through the night... or at least that's what someone told me. How many hours dictates sleeping through the night I'm not sure! I'll put him down between 11:30 and 12:30 usually and he's been waking up between 4:30 and 5:30 mostly. But, one day I put him to bed at 11:30 and he didn't wake up til 6:30, that was exciting! But, bottom line is I'm only getting him up once to feed him during the terrible middle of the night hours, so I'm happy. The best part is that on MWF I can make it coinside with the time the kids come (4:15ish). That's all I have for now!
