How to feel better about Co-sleeping?

My LO is currently 6 weeks and loves to use me as a human pacifier. I EBF and sometimes he will be feeding every hour or cluster-feeding between 7-11pm . By the time he falls asleep I do not want to wake him up and transfer him into his crib so we have been safely cosleeping However , I still feel guilty for letting him sleep with me. Im dealing with PPA and I often don’t get much sleep even when he’s sleeping since I’m constantly checking him to see if he is ok. He won’t last in the crib either and sometimes it’s better for me to have him next to me so I can tell he is breathing. How do you deal with anxiety and are comfortable with safe cosleeping?
