Great to hear from you, Chad, and Robert is looking wonderful! Now, as usual, I am the balloon popper in the bunch and have a few suggestions to make based on the videos.
Video 1: Please, please, please, do not handle a macaw the way you would a puppy. I don't know whose hands those were in the video but you do not touch a parrot's stomach (NOT EVER!) and you do not antagonize it that way, either. He was not happy on that video and you got away with it because he is still a baby but he will grow up and that handling is going to have real bad consequences once he is a mature adult and hormonal.
Video 2: Please make sure that the parts of his toys are not small enough for him to swallow and choke on - that ball he pulled out of the toy fit perfectly inside his beak and that's dangerous.
Video 3: You need to make the water deeper in the dish, he could only dip the mere tip of her beak in it.
