Alright. The title might be a bit misleading. Many of you may say "4 mo is still too young to fall asleep on their own."
I know. I have been sleep training DS. He does very well with the daytime naps, easily falling asleep with me sitting next to him. But he always cries his lung out for the nighttime sleeps.
I cannot understand this inconsistency. If he can fall asleep by himself during the day, why can't at night? Same bed, same room, same environment, same me next to the bed.
