We had that same fussy time up until my daughter was about two months (maybe even two and a half months)....but it definately started getting better around two months....I second the Miracle blanket...it isn't a special material but it wraps them in really tight and helps them sleep a lot better, as they get older they (at least my DD) was able to squirm her way out of a regular blanket swaddle and then she wouldn wake up and couldn't go back to sleep. Will your son take a pacifier? Maybe her just wants to suck during that time? We used to just trade off holding DD and rocking her and doing whatever possible to keep her from screaming. Also, you may try starting a bedtime routine at this age. maybe at 5 or 5;30 give your son a bath (this cna relax a lot of babies and my DD loves getting a bath!) and then swaddling and giving either a bottle or bf'ing, whatever works best (you could even pump while DH gives a bath and then give a bottle of EBM (that's what we do)....then put the baby down and maybe he will sleep better. Good luck and know that things will get better. I felt the same way as you at that stage, like I was a bad mom and couldn't figure out what to do do to help my DD, but honestly sometimes despite your best efforts there is nothing you can do and they just need to cry....it will get better!
