Are FlightSuits an option?

Me and Teeks are getting along swimmingly and I'd love to be able to spend more time with him. However, I've had trouble finding time to spend with him the past couple days.
Often my dad is playing loud music, which scares him, and sometimes the front door is open so that we can get some much-needed fresh air. Teeko will often wander somewhere he shouldn't be, either to bite someone or leave a 'sweet little bird surprise'. Teeko flies away when he's been spooked and there's almost always something cooking on the stove. Thanks to our house's crappy layout, having the bird out in any room but the bedroom is not only inconvenient but also dangerous. I'm concerned for his welfare and have been thinking about some options. FlightSuits have come up everywhere I look and I was wondering if you guys think it would be a good choice, considering my situation. Teeks lets me touch him anywhere, manipulate his wings, feet and flip him over.
I'm aware of some of the downsides of the suits (Bird might not tolerate it, 'diaper' is possibly unhealthy, leash sometimes not secure) and am keeping them in mind. If any of you have other ideas of how me and my little guy could spend more time together, or if you think FlightSuits are/aren't a good idea for my situation, feel free to chime in.

I use them only when we are out and about and there is a need for a leash to be involved. Leaving a bird to wear a harness just as a diaper for long periods of time can cause irritation and problems such as plucking. Potty training is a safer option (and there are no documented cases of bird dying because they held there poop that I can find, though people sometimes claim it will happen). As far as your house situation it sounds like your family needs some birds training and you need some extra things in place. Birdy needs a safe and entertaining place to play if he is just going to be loose in the house, like a play stand, etc, but it sounds like your house is not a safe place to have your bird out unless he is the only thing you are thinking about, so I suggest getting him a bigger cage and making sure you have the time to focus on him so he is not able to wander into danger. Also look into startle training, so the danger of losing him when he spooks can be deminished. Is he recall trained? That is another must!
