Welcome. Having two is not too much for many people. Will they get along - who knows. This is something that is asked a lot, but there is no one answer to it. Introducing them both while they are babies, I think, increase the chances that they will get along. But it does not guarantee it either. When you introduce them, do it in a place that neither one of them consider 'theirs' - a neutral space. I introduced all of mine this way and the two that are left still get along well enough to be out together most of the time. CAGs can be a good family bird, but some are very skittish and the large noise and sudden movement of children wouldn't work with those. Enjoy your time here and learn all you can - any information will serve you well when and if you decide to add a CAG to your family.
