My LO is 5 weeks tomorrow. Every night he gets exhausted around 7:30 or so. I feed him and put him down around 8pm for the night. He has this pattern or fussing/crying until around 10 every night. I have tried rocking him and soothing him to sleep in a variety of ways but he can't seem to let go and sleep. I nurse him and he falls asleep but wakes up right away after I put him down and starts fussing. He gets angry/overtired and pushes away from me/arches his body. So I've found he seems happiest swaddled and laying in his cosleeper with a binky. But inevitably he might sleep for a couple minutes then wakes up again or just loses his binky and fusses til I put the binky in again. I lay next to him in my bed with him in the cosleeper so i can soothe him and give him his binky. This pattern goes on for an hr and a half or 2 every night. He's so tired and miserable but just cranky on top of it. I can't help but think letting him cry a bit might do the trick of him releasing his pent up energy or finally getting to sleep. I've tried everything else but nothing seems to do the trick. However I don't want to do this while he's too young so I'm looking to other moms who are pro-sleep training and who have experience. I'm only referring to the period of 8 to 10 at night. Not looking to reduce feeds or anything like that. Just to get him to sleep for the night. How long was it before you let your LO cry? What age do you start putting them down drowsy but awake?

Re: STM's- regarding sleep training
I will be going back to work soon so we are going through the same thing with DD2. She gets super fussy if she is overstimulated. So we turn everything off in the living room or bedroom to help her body recognize its bed time.

As for sleep training DS 1 was an AWFUL sleeper and I didn't start really "sleep training" until 6 months because I just felt like he was too young before that. At 8 months we resorted to CIO and he magically slept for 8 hours after the 2nd night of it.
So I'd say do what you have to do short of crying it out (agree that it's too young but trust me I was almost ready to try it I was so tired), and hopefully babe will snap out of it sooner rather than later!! That 6-8 week peak of fussiness is no joke.
