I need help! DS is 4 weeks old. I want to start him on a bedtime routine but I'm not entirely sure how to go about this because of his sleep pattern. So he sleeps all day waking up every 2-2.5 hours to eat and falls right back asleep with the exception of 2 hrs in the morning and 2-3 hours in the afternoon . at 9pm I give him his bath(which I usually have to wake him for), bottle, cuddle, bed, HOWEVER he doesn't sleep. He's wide awake. He'll stay awake until about 12, 12:30 and then sleep again until 2. How do I fix this?
