Co sleeping & EBf

Hi....

Long story short my 8 month old son was Sleep trained at 6 months we had a good routine going, then he got sick and that’s when it started. I’m guilty of it I’m being used as a pacifier at night I love and hate it. I’m not sure what to do how to stop this bad habit. We are not getting the sleep we used to. If I try Ferber method again which was successful the first time how do I do it with my child who pulls him self up and stands now while screaming his head off for me to go pick him up 💔😫 any one go through something similar to this it’s so much harder now to try and put him to sleep on his own.
