Co sleeping.

Who else co sleeps ? My baby is 4 weeks and will not sleep without being in my arms. She is either tucked in my armpit /hip or on my chest. She has reflux so it does makr me feel safe to have her clothes but on the other hand I feel guilty that something could happen to her. I'v had her in my arms close to ledge of couch , and have even had deep sleeps while she was on chest. It terrifies me. But I'm so exhausted , and to atempt ar putting her in her bed or even beside me and to have her wake up and to have to start the sleep routine all over again just kills me when it's 330 am.
