Baby cries at night why?

How fast do you let him sleep after feed? Maybe can let him stay upright for 10min or so before putting him in his cot? If awake, some gentle massage on his arms and legs may sooth him and help him sleep better. Play some soft music in the background, darken the room a little if possible. However, if he cries louder when room is darkened, do odder him more light. Also, check his cot if anything is making him feel uncomfortable too.
