Ferber method fail

I don’t think I’ll be able to succeed at this with my kid. He is a relentless little guy as it is, and I tried it tonight and came back after 3 minutes of him scream his head off and he had rolled over on his belly and was in the corner of his pack n play like trying to get out 😖😖I tried to soothe him and his little back was all sweaty. Broke my heart. I don’t think it’s for us. Anyone wanna share their experiences/alternative methods?
