I think my guys just go over their baby phase and started acted more like birds. I will note that now that my mated pairs are 4 years old and they will still rush between my legs if I put a blanket over it so they can cuddle with each other in there against my leg.
Not sure how much you are cuddling with your little guy but when my guys were 7 weeks old, they would always be in my lap or wrapped up like a parrot burrito and I would take them everywhere. At night them would lay under my sheets against my side as I watched TV, of course I would put them in their bed when I went to sleep. My suggestion is to cuddle with your little bird as much as you want and also try and let it socialize with other people if the situation allows it. I take my guys to a local exotic bird store every weekend so they can see other baby birds and interact with other people, they even get their own stand when the peak breeding season is over so people can say hi. My male is a huge flirts with the ladies, does his mating gestures and gives them kisses.. all while his mate is screaming him to get back here or she is trying to get over there for a 3 way kissing session. I am sure there are more informative parrot lovers on here, I am just speaking from my own experiences.
