Hi Girls ...I really need some help please!!!

I am having sooo much trouble getting Jensen to sleep at night...and now I feel so confused on what to do...so Id love to hear how your getting your bubs to sleep or any advice would be greatly appreciated...Im feeling very down and out!

At the moment we dont have a routine, during the day I feed him until he falls asleep on the breast and then pop him into his bed...but he only sleeps for about 1hour or so then screams and screams so I end up feeding him again and so the loop continues!
At night its pretty much the same... Ill give him a bath, then feed till he falls asleep...but last night I tried to put him into his cot awake after his feed and he just screamed and screamed...so I went back in and gave him a cuddle and then leaving the room and waiting 10mins and kept doing this for almost 3 hours...and still he wouldnt settle at all!!!
Should I be starting a routine?
Or is he still too young (hes almost 6 weeks)
Ahhgrrrrr Im soooo confused girls...it brings me to tears as I so want to do whats best for him....
Thanks for taking the time...
love Cyn
