DS is 15 weeks old and has been sleeping well at night for a few weeks now. He falls asleep around 7:30, gets a DF at 10:50, and then has one early am feeding before getting up for the day around 6:30.
He has gone to almost 5am before, but only once. He typically wakes between 2 - 3 am for his feed. The problem is if he wakes at 2, he doesn't sleep until 6:30 - he's up again around 5. If he eats past 3am, he'll sleep until it's time to get up.
Doing the wake-to-sleep has helped him get to that 3am mark or past it, but after doing it for three nights I might get one or two nights out of him on his own, and then he slowly works his way back to waking up earlier.
Do I need to keep up the wake-to-sleep longer than three night or should I just let him wake at 2am? I would much prefer the 3:30 waking!
