Maybe making progress on sleeping through the night

Declan was a bottomless pit last night. He ate 11 ounces before bedtime, when he normally eats 4-6 ounces at a feeding. I hoped he would sleep straight through, but apparently not. He got up at 2 am and Daniel fed him 2 more ounces. He woke again at 4:30 am, but put himself back to sleep. That's a major improvement! It's the first time he's soothed himself back to sleep at night without getting fed.
