Hello BRD and welcome to our family.
So glad to hear you are doing the research before plunging in to get a grey, they are complex animals but if you really want one then you can make it work, with children, other pets and occasional vacations. Many here have children and/or other companion animals and they all get along, with a few bumps along the way, very nicely.
We used to travel with our grey when our son lived in the next state away from us, we would take her in a travel cage and she rode nicely in the back seat sometimes chatting away as we traveled 4 hours by car but now that our son has moved closer to home about the only time she goes in the travel cage is to the vet or outside for a bit of sunshine. Its a good idea to get them used to being in a travel cage if you are planning to take him/her along so they love going in one.
