Most of the week I am not with Grace so I don't know the exact schedule but here's my guess:
8-9 wakes up. Sometimes surprises me at 7, but rarely.
11ish - Eats and nap for anywhere from 30 min to 2 hrs. Depends on if I am with her napping too.

2 or 3 -Eats
5 or 6 - Eats
Sometimes there is a small nap in there.
7 - Short nap
8 - Bath and bed. DH has a great bedtime routine down and she falls asleep pretty well. As for how long she sleeps it depends on the night. Last night she went from 8:30 to 4 without waking, but a week ago she was waking every 2-3 hours to eat.
Do you feed Ian before bed? And when he wakes at night is he eating or just being comforted back to sleep? Has he slept through the night at all before? Like I said before, Grace has her nights where she wakes all the time. If I go and get her I nurse her back to sleep. If DH gets her he just rocks her for a minute.
