What can i do to get my daughter to sleep ?

My daughter is about 5 weeks old. She is colic! My first daughter was colic as well so I know some of the tricks, but it seems like Lisa *my newest edition* is even more colic if thats possible! I have to either hold her 24/7 or be bouncing her in her bouncy seat. My fiance and I are having relationship issues becuase of this bc he has no patience for a screaming baby. Hes alot older than me but its like he works during the day and when he comes home if our middle childs getting tired n whinny he says thats it off to bed n puts her in her crib so he dont have to deal with her. I know im a stay at home mom but its like i am human i cant listen to Lisa*the colic baby all day and all nite. When she first started being colic she would only sleep in her bouncy chair. Now its like she mite fall alseep in it but as soon as she wakes up in 3 hrs for her feeding she will not go back to bed in it. she screams n she dont wanna be in it. the only way she basically sleeps now is on my chest. And i cant listen to her screaming all nite long bc ive listened to it all day plus my other 2 children are are as well under 3. I love my kids to death and dont love my youngest any less bc of this constant crying bc i no its no her fault but i need suggestions on how to get her to sleep in her crib at nite bc shes is horribly colic. Even if i just get her to sleep in her bouncy with out screamin ill be ok although id perfer her being comforatable in her crib. I just need to attempt to get her to sleep more @ nite. I know shes still young so she wont sleep thru believe me i no its my responsiblity to get up with her at nite to feed every 3 hrs thats not my problem its that im not supermommy im human n want to sleep n have her sleep comfortably, bc her dad has no patience n his theory is i gotta work ur home all day u do it or go out n get a job n ill stay home ....he wouldnt last bc he has no patience for her crying...please help me...ive tried everything i can think of!
