Just an FYI: Amazons bit also!!!
Please take the time to 'Read Out Loud' to your Amazon several times a day for several weeks! My recommended reading would be the Understanding Amazon Body Language at the Top of the Amazon Forum (highlighted in light blue). Both you and your son can take turns! This does two things: First sets in both of your minds the basics of Amazon Body Language (communication) and second, it works to build a stronger bond between everyone!
NOTE: Amazons can and do become one person Parrots! By everyone being involved with the Amazon (socializing with everyone) that Bond will be less of an issue! Everyone gets to provide the Amazon with so thing that that Amazon enjoys. As the person that the Amazon Bonds with becomes clearer, they get less of the good things to provide and the others then get those items to provide. The goal is that everyone is liked and not everyone is on the outs and only one gets to handle the Amazon! Begin working now to assure that everyone has a open relationship with the Amazon.
Please also take the time to read the Huge Thread Titled: I Love Amazons - ... As stated, this Thread is Huge, but contains very important information in Love and Living with Amazons
FYI: What Species of Amazon do you have?
Always remember: Amazon's Rule!
