If you are planning on housing some of the baby furniture in the rooms that Keywe frequents, such as a crib, or a changing stand, then I suggest that you also put those in place before the baby arrives. That way Keywe will be used to them and won't blame the baby for "bringing" them with him or her.
Congratulations on your new baby, and I second Berna's comments well done for not thinking about rehoming your parrot:)
