Your title made me laugh so sorry lol

How old is you little conure and how long have you had him?
Mine was a complete nightmare for many months and if I'm honest I thought it was never going to end and I hate to say it but I actually regretted getting him for a short time because nothing appeared to help. Anyway I continued ignoring him and eventually won through, if I knew he was biting for attention I would put him down and leave the room for a few seconds these days he never bites unless I'm not paying attention or accidently hurt him by catching a pin feather.
I don't know if its normal for such an extended nippy phase but I do believe it would have passed quicker if my boyfriend ignored Ollies bites too instead of screaming like a girl lol. For that reason I would say you both need to work together on this rather than both working at opposites. For the record my boyfriend still has problems with Ollie biting frequently, I think that says alot.
