Welcome home to you and your new baby boy, I know you must be thrilled to be picking him up today. Since people far more apt than me haven't been able to locate the original post for you, I figured instead I'd give you my 2 cents on the first few days. And anyone feel free to chime in if you disagree with anything.
I think the single most important rule, is just to let your new boy set the pace. There isn't anything wrong with socializing with him early, and if he was ready to jump in your lap the moment he got home and hang out, that's absolutely fan. You just don't want to try and force him in to coming out when he isn't ready.
And honestly, he may be ready much sooner since you have been visiting him so much. He may WANT to be with you the second he gets home, and there isn't anything wrong with that!
Make sure his cage is all set up before-hand so that if he *is* a little nervous, you don't have to keep reaching in and out of his cage.
And, if he does need some time to acclimate which is also fine, it's still great to spend time near the cage talking to him, reading to him, letting him just get a feel for your presence and your voice, and just the overall vibe of his new home.
But again, as long as *he* is comfortable with what is happening, there really isn't any "to soon". To soon is just when we want them to do something they AREN'T comfortable with yet.
Again, great to have you, and can't wait to see and hear more about your new guy.
