When to transition baby into crib

Megan

My sweet baby is 8 weeks old. I have her sleeping in a bassinet beside our bed, but in turn am getting little to no sleep at night. I wake up to every little sound or movement she makes. Anytime I place her in the crib, it is very hard to soothe her and calm her. Any tips for transitioning her into the crib? Thanks in advance! Sincerely, one tired momma.
