Sleep

I rock and cuddle him then lay him down. On nights he's refusing to sleep for a while I let him walk around his room I do not turn lights or sound on the night light is enough and he comes to me when he's ready for cuddles to sleep again. Mines 11 months as well.

This could very much be because of his sleep schedule during the day! He could be undertired or overtired

What’s his schedule look like now?

Not much advice but I'm compelled to share the wisdom that CIO is both unnatural and harmful, no matter what the last few generations will try to tell you. I'm glad you aren't doing it anymore. That said, your neighbors can get ear plugs and shit. Babies cry, all night sometimes if they're colicky or abandoned (which happens with CIO). If they don't like it they can move to the woods or get a house. We're trying to fix our sleep schedule too. It's hard 😖
