Yes, I also do not believe in not reacting when hurt and actually make a big deal out of it
. Now, I have no real personal experience with babies because the only babies I've known were lovebirds, budgies and tiels which are so very different from the larger species and from their adult counterparts but, for what I have read, he might not be really bluffing but simply growing up.
Babies are always extremely complacent, they always step up when we ask them to, they are always happy to see us, to cuddle with us, etc but as they start growing up and feeling more self-assured, they start becoming more independent (especially species like IRN's which are more aviary than companion). And this means that they might not want to step up every time we ask them to. I am not saying this is the case with you but I have noticed that most people who claim their baby bird started biting them when they ask them to step up are actually asking them several times in a row, not taking into consideration that the bird already told them it doesn't want to. Personally, I ask them once and, if they don't do it, I leave them alone for a little while and ask them again later (and this ONLY if I really need them to step up, if I don't, I don't even ask a second time).
