you mean like you get fast food and he reaches in your food?

We've SO MANY conversations with SS15 about this! I understand you're hungry but eating an entire pack of salami lunch meat because it's easier than making a sandwich is NOT acceptable! Or eating 6 ice cream cones in 2 days or eating an entire box of crackers in less than 24 hours.

It's a never ending battle to let him know he can eat if he's truly hungry but can't eat all the junk food or all of the whatever we bought because it's for all 3 of us.

I've said it many times but...I do NOT like teenagers!

As a teenager he is old enough to understand what is acceptable behaviour. I can understand if he has never been told - so you may need to tell him or help him. Set the ground rules. Repeatedly doing the wrong things is willful defiance IMO.

Many people don't have basic manners or basic table manners because they have never been taught this. (I am talking about the basics: no baseball cap at the table, chew with your mouth closed, swallow and then talk. It is not the finer points of placing a knife with the blade edge facing the plate or removing the service plate/ charger before the dinner plate is set down. I am not talking about that. I am talking about not kicking other people's chairs or sticking to the food in your own plate.)

Your SS needs to be careful he doesn't get is hand slapped for his rude impertinence. I would slap it!

funny my son always asked, he never just take what he wanted, he knew, pantry you ask, kitchen you take..

then came Aergia, she gave a flying duck and would take what ever she wanted, I stopped buying things for the house, and started locking the pantry lol

Mil and BM2 let rummaging/snatching-ss6(then 4) looked greedily at my purse everytime and then would go in it when i wasn't loking. Many times he would snatch things he wanted out of any hand without consequence when with mil/bm alone
Everytime he would rummage/snarch at my housd he would get disciplined by DH or me.
Fast forward:
We are at the park.ss6 sees a toy he wants but doesn't see us. Snatch!!!(he still does it when we dont look-lol xgildren are sneaky!)
The child whose toy it is is holding an end also.
I get up and yell:Ss6 come here!
He looks up drops the toy and cones to me(parents in the park are stunned)

My two teenage SD's are overweight and they like to eat.. A LOT. I had to start telling them not to eat everything all at once as we couldn't keep enough snacks in the house. One morning, the older one wanted to make breakfast - she made French toast, eggs, bacon. Well, the loaf of French toast was very large and slices were thick. I figured she'd make 1 or 2 pieces per person. Nope - she made the whole thing. And then her and her sister proceeded to wolf down most of it. SO stopped them at piece #4. It makes me sick to watch them eat.

My skids want a snack every hour.
Ss12 asks and I usually tell him what to have.ss6 is nonverbal but starting to talk so he was bad with snatching/rummaging(never disciplined at all until I came along). Also BM2 only feeds him what he likes(bread and candy bc he is ASD).
He stunned me last week by actually asking for food:may i have breakfast pleaae. And pulled me to the bacon in the kitchen
I am the only one who can make SS6 try other foods(bbq pork,cheese,chicken,peppers,potatos)bc he knows he has eating rules at my house and consequences if he disobeys or tantrums (these deserve a post in themselves).
I remember the first time ss12 tried tto only eat what he wanted off the plate(surprise-the steak). He got up to fo for seconds of steak while leaving all else on plate. I like it but not foing to eat it. He was proptly told by hubs to eat off his plate until not hungry anymore.

My two step children eat all the time. The eldest is the worst because she has no manners. It is disgusting.

They want to eat snacks and crap. They get very angry when fiance does not have junk food in the house.

I love to cook. The eldest SD hates my food. I was amazed when she said, "You can not eat green food!" She refuses to eat vegetables or fruit. She is 14 and 50 pounds over weight!
