How can i stop my cockatiel being aggressive towards my hubby and kids...charlie is 6yrs old and ive had him for just over 3 yrs.his tame with me and loves to have cuddles and kisses with me.i think he thinks of me as his mate thats why he doesnt like hubby/kids.but really need to do something about it.was thinking about getting another cockatiel (female) but not sure as been told that i would more than likely lose the bond i have with charlie..so dont really know what to do so any help/advice would be most grateful.x
