Aunt playing favorites-need advice

[Guest guest]

HI everyone I hope you all had a wonderful holiday. I need help with an

ongoing family problem. My stepsister has always favored my oldest son

he is 17 and my youngest is high functioning and 6 years old. So as we

all know too well my youngest behavior is not always the greatest but we

work hard to help him with his emotions. So at Easter I invited the

whole family over and he had a meltdown stepsister felt it nessecary to

once again reprimand my child in front of me and his dad and also told

him that someone should " ring his bell " for his behavior. I blew my top

and pretty much sent everyone home. So then comes his birthday and

nothing from stepsister and then comes 17 year olds birthday and of

course there she is with a card stuffed with money for him. So now

Christmas I made other plans to not have to see her and she leaves a

card at the grandparents house, probably stuffed with money, and again

and nothing for the 6 year old. I want to give her the card back and

tell her if she can't treat both of my children the same not to give

anything to either one. My oldest will be 18 next year and she can do

what she wants then but for now I still call the shots with my kids and

think that they should be treated equally. Please let me know from an

outsiders point of view what you guys think. If you think I am wrong

please let me know. If you have a more tactfull way of making my point

please let me know.
