Help baby will only sleep on Boppy

I bought a Boppy lounger, and made the mistake of letting her use it during the day. But now when I put her In her bassinet at night she is wide awake and crys untill I pick her up. I even feed her first and wait until she is asleep and gently put her in the bassinet. Does anyone else have A Boppy obsessive baby? She is 3 weeks old. I'm not sure what to do! That's her In my profile pic snoozing on it : D
