so my 15 week old has been sleeping through the night since about 9 weeks. He usually sleeps 5:30pm-6:30/7:00am. It was amazing!! And I was so lucky!
But recently he has been waking up at 4am, which throws off his feeding schedule for the day. If I put him to bed any later than 5:30ish he wakes up SOONER, like 3:30am!!
And when he wakes up this early he doesn't get a bottle and go back to sleep, he wants to play and be awake for a good hour and a half before going back down to sleep!
Does anyone have any advice on how to get him back on schedule? I've thought about trying cereal since he is almost 4 months and see if that allows him to sleep longer.
