My trips are 12 weeks old. We did a 3 hour schedule through the day (and like the pp said its hard!) But after they were about 4 weeks old they only woke up once through the night and then when they were 10.5 weeks old (6.5 weeks adjusted) they started sleeping 8-9 at night, most every night.

When they started sleeping better at night they were taking a full 4oz at every feeding (and I had to push them to take it or they would only eat 2 or 3oz each feeding) and started taking less and less at night, finally the night after it took me an hour just to get them to eat 1 oz when they woke up in middle of the night, they slept straight through.

There have only been about 2 or 3 times in the last 2 weeks or so that I have had to feed them in middle of the night and I only give them a couple of ounces to hold them over till the first feeding of the day at 7:30am. After they started sleeping longer at night, I went ahead and moved them to a 3.5 hour schedule, so they are getting 5 feedings a day instead of the 6 feedings on the 3 hr schedule and they are still doing fine. I still think its a bit too soon (for us) to go to a 4 hour schedule just yet because they only get 4 feedings a day on a 4hr schedule and I am afraid they will start waking up hungry at night again.

I have decided we are going to start rolling back the time of the last feeding (10:30pm) slowly to make them stretch the night time sleep out until we can drop that last feeding completely and THEN we will go to a 4 hour schedule.
