How do I get my son to love me again?

My son was born Jan 24th he is 9 wks old today. To make a long story short my son has really bad colic and we give him tummy soothers to help. Anyway me and my son were just fine until my mom lost her job and came to live with us. At first she was just really helpful. Before she came I had my own routine and was able to put my baby to bed myself. Then the colic kicked in and sense I had to go back to work two weeks after my c-section she keeps him during the day. And when he became colicy and I have no idea what to do she keeps him. Well know his colic has calmed down and when I try to put him to sleep or put him in his bed he just cries and cries, and when I give him to my mom he stops. This is really hurting my feelings I never see my son not in the day or the night. I want to be his mother I want to take care of him I just dont know where to start!!! I dont want my son to cry and be miserable because he is more compfortable with my mom My mom also tells me that he thinks she is....
