aww lol i like yoshi that dragon from mario brothers lol
try puttin a perch on the door, an train her to go onto door to come out, i dare not put my hands into nuts cage, she'll prob try to skin it for me lol, but she will step up off the door or roof of her cage for me (if she feels like it) :09:
or continue using wooden spoon as a hand perch, but again try to get your bird to come onto door etc, that way you are not invading its safe space
this nipping, you need to be firm, but at the same time avoid doing things that leads to her nipping you! because these nips will turn into bites an they hurt!
with these birds its a case of asking them if they would like to! rather then telling them to do something, even if its in there best interests lol
you need to learn its body language, turning even slightly is a polite no, if you keep ignoring this, they will bite, an it creates bad feelings all around!
my nut is fully flighted an will fly an attack me some days, if she is that way out, or even run at me, so when petting keep your face out of reach, and best for now to have her on your wrists/hands, you really dont want an angry bird on your shoulder
best thing to start with for bonding is head rubs

wriggle your forefinger to it (your wife must use same signal) when you want to pet her, (not down its back, as that is sexual, and will create problems later on) watch her eyes if they pin, no turning of the head its a yes
you may find after a time she will bow to you, thats another indication she wants a head rub, be with you (not to be confused with lowering its body! with beak and wings parted, thats attack stance!)
while petting watch her body language agin lol these are sneaky birds an will sneak in a nip, if it thinks you are owed one

or you are not doing it right or for to long!
as for toys go for kabobs/shredding toys, bells, nuts not into her toys other then things she can shred or destroy, and some foot toys i hide nutri berries in some of nuts toys
relax on training for now, as your bird does not sound to bonded to you, just start with the basics, but if your birds not in the mood for training, it won't do anything for you and you will both end up fraustrated (also your wife needs to be involved as well, or bird might only do what you ask it, later on)
training needs to be fun! try this, you come home an great bird in its cage, sit down an eat some fruit! your bird will literally ask to be out of its cage, if not offer it some, but she needs to come to you, when she is happy coming to you, start the step up training, and then the step down, it'll soon get the idea what commands mean, right now it has no idea what you want of it, or its place in your flock:52: and most importantly what its routine is
also your bird should be getting at least 10hours of sleep at night and a daily bath, (i spritz nut with warm water, every other day) not all birds like water, nut does not mind gettin spritz if she is on some1 lol
sorry for being sooooo long winded, hope all tghis helps
